Message-ID: I recently bought one of these, just before the $100 discount started: https://www.costco.com/Dell-Inspiron-Desktop---Intel-Core-i7---2GB-NVIDIA-Graphics.product.100344519.html I think they'll give me the $100. But, anyway, the reason I'm writing to the list is that I've had some peculiar problems and I'm wondering if I have a bad computer or one that has some kind of incompatibility with Ubuntu. Installation of Ubuntu 17.04 was a breeze. I kept the Windows 10 in a 100 GB partition. I started copying files from a USB 3.0 external drive, but sometime after the screen blanked I tried to enter my password at the login window and the system just hung -- it never accepted the password, the screen froze, it seemed to take no input from the keyboard and while the mouse cursor moved on the screen, clicking had no effect. Often when I press the power button, it comes on for about a second and then turns off. I saw that happen once after powering off -- it turned on for a second, then off again. That seems odd. I had to start in recovery mode. That seemed to fix it, but the next time I used it, it got stuck again and I had to use the power button to shut it off. Does this sound like bad hardware? Or could it be some kind of driver issue? I'm also wondering what is the easiest way to get the old memtest86+. Didn't it used to be in the Ubuntu ISO? I thought it was there. I would have run it already if it was easily accessible. Thanks in advance.

I reinstalled openSuse and this is what I get from uname -a: Linux 4.11.8-1-default #1 SMP PREEMPT Thu Jun 29 14:37:33 UTC 2017 (42bd7a0) x86_64 x86_64 x86_64 GNU/Linux I don't know if you use suspend/hibernate, but I had been doing some of that prior to this happening. My guess is that using those had something to do with it. On the previous install I picked the KDE desktop. For this latest install I chose Gnone. I noticed Gnome doesn't mention (at least that I've seen) anything about suspend and hibernate like KDE did.

When your Ubuntu install is up and running, disable the Screensaver and/or the auto-lock the desktop feature. Wait and see if this fixes your locking up/non-responsive issue. Later on, if you like, re-activate the Screensaver and auto-lock.

Large files and statistical analysis using that "large" data is subjective, and it largely depends on the application. But I would say that most people who do things like this on a workstation are probably easily satisfied with a bunch of memory (and possibly fast drives). Nothing beats Linux in memory management right now; this coming anecdotally from me, but most likely true. Video editing is demanding. My cousin used to have special hardware to do all of his editing back in the day. Today, it is not graphics cards that are pin-pointed bottlenecks as much as it is drives and memory bandwidth. I envy the patience of those who do video editing. My "control-freak" character when it comes to manipulating video-data rests on scriptable and/or interactive use o MPlayer (through a unix pipe). If you are not doing anything with that piece of magnificent software, certainly invest some time learning about it. It may change your life. For serving files I'd ask my trusted expert "rhayman" to point to solutions. (The person who opened up for sale two of his 4U rack-mountable units.) The key is to have robust recovery, in my opinion, but for scratch space for data manipulation, say large resolution video, you may need SSD or fast RAID or both. (Alternatively, get a self-improvement book on patience!) In full disclosure, my high computational demands are not easily satisfied with 1000 cores and 1000 x 1GB of RAM, and I compete for such resources with others. Bottlenecks for us are large data visualization and what is called "mesh generation" in engineering and simulation. In both cases graphics hardware and generous amounts of RAM help. But some of us rest on clever coding and some quite sophisticated distributed-parallel software packages (HDF5). My 1GHz Pentium still satisfies all of my coding and writing/reading needs and other essential network services! I could probably do all that on a Ras-Pi.

We do numerical simulation where I work. It is a lot of fun for the most part. I used to use the MSI's machines a lot when I was a graduate student in the late 90s. I had access to the SGI Origin and IBM/SP at the time. I did not use the Army Center's CM (Thinking Machines) or any of the Crays. Circa 2000 we built our own cluster and since then we have had 5-6 generations of them in our basement, all Linux. No, I do not mine for bitcoin! > About MPlayer -- your comment is intriguing.

You can put it in "interactive mode" and have it listen form commands coming from a unix pipe. You can sit at the other end (even typing by hand) and send commands; seek, crop, rotate, dump frame, etc, etc. The beauty is that you can manipulate its functionality without really having to code anything that uses its codecs or ffmpeg and all of that. The functionality becomes a black box via scripting on the command-line, or interactively through the pipes. Invest that time in it. Here is an example of extracting individual frames from a video: 'mplayer -vo jpeg -frames 1 -ss "offset"' # "offset" is a number Here is an example of using a "video filter" that crops and rotates the image, and it drops every frame to a PNG image: 'mplayer -vf crop=172:622:170:0,rotate=1 -vo png video.mov' (The input video was an Apple's format; this is autodetected.) I believe this is a top Open Source Software project.

It's worth noting that Amazon sells a "No Special Offers" version of all their Kindle devices which do *not* show ads. Naturally, they cost more. They also let you disable the ads post-purchase (though they do charge for it, of course).

Message-ID: *working with xrandr 1.5 not finding how to connect second or third gpu* ------------------------------ Greetings Running debian buster (testing) using lxqt. Have 3 nvidia 570 gpus and 4 1920x1080 monitors. Have had this system now for almost 5.5 years and have had it running the four monitors all that time. Updated to buster (new testing) and found that there were some issues with proprietary drivers nvidia 375.66 - - - was having one gpu halt and upon reboot things seemed to work again. The time between reboots was getting down to less than 12 hrs when I landed up with a system with corrupted networking on a reboot. So in the process of re-install I decided to try the Nouveau drivers instead. So now I have a one gpu 2 monitor system available. Got to very much like the four monitors for my work layout so I want the other two monitors working. Using xrandr I can see Provider 0,1 and 2. DVI-I-1 and DVI-I-2 are connected. DVI-I-2-5 and DVI-I-2-6 are listed as disconnected. I have been able to create a virtual screen of 3840 x 3000 which is how I had things before this reinstall using $xrandr --fb 3840x3000 . Tried $xrandr --setprovideroutputsource 1 0 no changes looked for pci addresses found 01:00.0. 02:00.0 and 03:00.0 Looked in the kernel log and all I can see is a error code of -19 (for both Provider 1 and 2) which, after a lot of digging, seems to be saying "no such device" Tried $ xrandr --addmode DVI-I-2-5 1920x1080 then DVI-I-2-5 still shows as disconnected but with a resolution of 1920x1080 60.00 Next I tried $ xrandr --output VGA-2 --mode 1920x1080 --pos 1280x1280 --rotate inverted result - - warning: output VGA-2 not found; ignoring It used to be that this setup happened in xorg.conf (and was a monolithic file), then things were changed to files placed in /etc/xorg.conf.d (as individual descriptions - - - ie. devices, monitors and AIUI screens) and in my system these kind of files are now in /etc/X11/Xsession.d but there aren't any to do with graphics issues. Any information I haven't provided that would help others help me? I can't find any guides on how to setup xrandr to use multiple gpus AND more than 2 or 3 monitors (usually from only 1 gpu). Most of the randr information I can find is for at newest randr 1.3 and I have 1.5. Randr 1.4 is where the multiple gpu option was introduced so it should be possible but . . . . I've found https://cgit.freedesktop.org/xorg/pr...oto-1.5.0#n160 likely everything I need is hidden in this file but for the life of me I can't figure out what commands to use. If I were an expert I wouldn't be asking but I'm not and there are no examples to follow (or try). Suggestions please? (Maybe do I have to go for newer proprietary drivers? (rather not I sort of like the no issues right now with Nouveau!) TIA Dee -------------- next part -------------- An HTML attachment was scrubbed...

Important stuff, too. I rattled some cages on Friday that might give support for this. Out here in the boonies Cellulose Biomass is growing at unprecedented rates with no market. Lumber mills gone, pulp paper gone, grass hay that won't feed a cow. But I saw some local celebrity experts on TV show 100 year old Hinckley fire photos and thought some search for modern biofuel science skills was about time again. After the usual mix of constructive contacts and jerk bureaucrats I discovered that the U of MN has some activity with David Morse in Chemical Engineering, etc. Not exact, but close as any, biopolymer computer modeling. The Feds had to roll back Cellulosic Biofuels mandate because MN bureaucrats fell on their faces, as usual. Burn up money and beg for more, failure is very profitable politics. So we need to pick up the pieces and accept the baby steps made to compete with the big world. I don't know how it fits into numerical analysis supercomputing, but I told the couch scientists to "copy fire." Fire is all "photochemistry," and solar energy can be stored directly in melting cellulose; just like making steam from ice. Anyway, a lot of computer geek stuff going on at the U of MN around this topic, as well as electric cars, etc. As once said regarding the future, "If you have no plan any path will get you there."

I wish I had time and unlimited internet out here to watch; maybe sometime. Normally, a speaker tells you what he's going to say, says it, then tells you what he said. As for science, I got a now related paleontology professor to accept that Darwin was an ignorant, and Friar Gregor Mendel was a profoundly successful scientist. Remember, I also studied and did well in advanced genetics; but that is off topic. There were two points of my note to your TCLUG numerical simulation reference. First, Cellulosic biofuels are a top global priority. Whether climate, economics, natural resources, population, security; nobody will dispute this. I don't need to swim upstream in a political sewer to advocate scientific inquiry using computer modeling and databases people are bragging about. Second, Minnesota has cellulose. If Richard Dawkins and his theater audience can help develop some science that works I'll sit in the front row and applaud louder than anybody. Finally, I'll believe fire is photochemistry until somebody proves otherwise. It might be worth doing more quantum mechanics and less thermodynamics in you computer simulations.

Instead I made an effort to find some scientists in Minnesota interested in advanced biofuels. Plant growth is as out of control as mosquitoes, and forest fire smoke from Montana to California now covers the Great Plains. The leading scientists at the U I've found are Iranian Physics Ph.D. student Taher Ghasimakbari, and profs. Shri Ramaswami and Bo Hu from BBE. I've been pushing the technologies they are working on for 25 years regarding climate and agriculture. This is how the internet worked, too, when Mark Dayton was commissioner of energy and economic development and Rudy Perpich was the brainpower state governor and the U was all supercomputers. It looks like you will be buying farm and energy technology from Asia now, just like modern electronics.

If you can live with increasing stability from where you currently are, then stick with 17.04. If you cannot live with this increasing stability, downgrade to the 16.04.2 LTS version. Personally, I stick with the LTS versions and upgrade to the next LTS version at the end of its support to ensure that as many bugs get fixed as possible before I upgrade to it.

Compiling software and dumping it on top of my systems is never a problem in my hood; backups will recover any wrong-doing very swiftly, at most at the cost of a reboot. This is going to be on Slackware, so it will be pretty easy. And I will report back.

So instead, the meta data says which blocks should be all zero. Look at du -h on the file, vs ls -lh. The problem you have is that scp/rsync etc are not preserving the holes. All the empty blocks are being allocated on the disk and take up real space. cp can handle such files, read the man page about sparse files. Another option i have used in the past it to create a cpio archive using --sparse, copy the cpio archive over and then unpack it, again with --sparse.

I ran checkvv on that volume (from 3par) and it came up clean. However, I do get a lun mismatch warning when mounting it but it seemed informational. The target drive is physically installed on the Linux box. It came up clean when I ran fsck. I am wondering if it is an issue with the volume being thinly provisioned. I am going to move the file into a thick provisioned volume and see if that changes anything. BQ_END -------------- next part -------------- An HTML attachment was scrubbed...

Actually < GnuRoot Debian >, which appears to be Debian 8 (jessie), has a March 2017 update date, therefore, I think that is the one to use! I just use < GnuRoot Debian > through the terminal rather than bring up X and an xterm (I think X is via X11-server-that-speaks-VNC) since the screen is a smartphone screen after all, and I have 1920x1080 on the screen so every button is way too small!! I used it on these Samsung Galaxy S-series: {S2, S5, S7}. [Recently my S5's video fried so I ebay-bought an S7.] First off, the important thing is, YOU DO NOT HAVE TO ROOT YOUR PHONE! It seems pretty capable, although not everything will work. For one thing, I think you have to run as user root. Your home directory (/home) is on your VFAT internal flash drive (path is < /sdcard/ > although it is *NOT* the external-SD-card but *IS* the internal storage). Path /, on the other hand, is, I believe, some kind of ext#, although, annoyingly < df / > says rootfs. At any rate, your /sdcard/ doesn't let you execute--has noexec, no doubt, directories you create under / will let you execute stuff. Further, your directories under / will have the nine permission bits handled correctly, etc. I have used < gcc, make, perl, emacs, shell scripts (/bin/sh), bash, traditional-nc (nc is netcat), ssh (client), scp (client), sftp (client). IIRC, I had trouble trying to install < sshd (i.e., the ssh server) >. I didn't try because I didn't care to have one: *apache* server. In my .bashrc, I have the equivalent of: TZ=:America/Chicago HOME=/com export TZ HOME and I did < mkdir /com >. I also added < $HOME/bin (i.e., /com/bin) > to my PATH. So, if I want to use internal storage (VFAT), it is at < /home >, and if you want to use < what I think is EXT# but is labelled as rootfs >, I can use ~ (which is /com). You can use whatever name you want other than the "com" part of < /com >. That's just what I decided to use. [Etiology of com (what I think is a better name than "smartphone") is: com = com com = (com)puter (com)unicator.] Now, you can easily get to, on your Android file-management-program on the outside of GnuRoot, you use path < /sdcard/GNURoot/home (capitalization may be incorrect) to get to the GnuRoot-path of < /home >. The least annoying keyboard that I've found (it is still annoying in that sometimes arrow keys don't work in emacs) is: NextApp So, to get < emacs > to your Android "smartphone", do this in GNURoot Debian: apt-get install emacs ==== Sorry for the sililoquoy. It's just GNURoot works so well that I am excited about a useful Linux in my pocket. ==== ~ Steve ~ On Sun, Jul 30, 2017 at 02:24:01AM -0500, Mike Miller wrote: > Re: GNUroot -- I think we're supposed to use this one now: > > https://play.google.com/store/apps/details?id=champion.gnuroot&hl=en > > Mike > > On Sun, Jul 30, 2017 at 2:20 AM, Mike Miller wrote: > > Have you tried GNUroot on your Android devices?
