[arch-general] Handling GeForce GTX 850M GPU on Arch Linux
by caocoa＠mail2tor.com 16 May '15

16 May '15

Hello all, I've juste installed a new computer and I feel like I'm having trouble with my NVIDIA GPU but it could be something else so I've enclosed detailed output. As you can see in [lspci] output, my GPU is `NVIDIA Corporation GM107M [GeForce GTX 850M] (rev a2)` whose specification can be found in [specs]. The trouble I'd like to solve has the following symptoms: → Sometimes during booting process, it issues a lot of lines like `nouveau E[ PFIFO][0000:01:00.0] SCHED_ERROR [ UNK06 ]` (see [dmesg] output for full details). This seems to appear randomly: somtimes it has to reboot two or three times before being able to boot correctly, sometimes it just needs once and doesn't have nay troubles. → Some other times, windows appears to stop responding with no reasons. I have to mouse the pointer off so the window display will unfreeze and then I can put the pointer over again. I've found it seems to be related to lines like this one `nouveau E[ PIBUS][0000:01:00.0] HUB0: 0x000001 0x00000002 (0xbad00100)` in [dmesg]. It starts at timestamp 28.115820. → Sometimes, even the window manager (Gnome) freezes and I have to go to a tty to have a chance to get it unfreeze. It doesn't always work then sometimes I have to reboot my computer because it has become absolutely frozen (no mouse, no keyboard, even the keyboard CAPS light responds no more). → Finally, in Arch Linux I've become used to have X server started over tty1 and tty from 2 to 7 free. Actually, when startup reaches the end without faults, it start X server on tty1 then GDM (Gnome Display Manager) is shown on tty1 but once I log in to my account, my desktop is shown on tty2 and tty1 keeps displaying GDM. I'm quite puzzled by this and I don't know whether the last symptom is a bug or a feature (maybe multiple user simultaneous outputs). I've also enclosed for your information my [Xorg.0.log] file and [lsmod] output. If it's a bug, which software should I fill a bug report to? nouveau driver, X, GDM, Gnome? Just feel free to ask any further data you'd need about my configuration. Thank you in advance for you reply and have a good weekend!

[arch-general] Read permission for group
by Ralf Mardorf 16 May '15

Hi, user 1001 (chuser) is in the group of user 1000 (rocketmouse). Folder and file have read permission for group 1000 (rocketmouse), but user 1001 (chuser) can't read the file. Do I miss the forest for the trees? [rocketmouse@archlinux ~]$ id chuser uid=1001(chuser) gid=1001(chuser) groups=1001(chuser),10(wheel),50(games),91(video),92(audio),93(optical),95(storage),100(users),1000(rocketmouse),108(vboxusers) Path and file permissions [rocketmouse@archlinux ~]$ ls -ld /home/ /home/rocketmouse/ /home/rocketmouse/.gtkrc-2.0_openbox+jwm drwxr-xr-x 4 root root 4096 Apr 23 10:14 /home/ drwxr----- 100 rocketmouse rocketmouse 4096 May 15 17:22 /home/rocketmouse/ -rw-r--r-- 1 rocketmouse rocketmouse 152 Oct 16 2014 /home/rocketmouse/.gtkrc-2.0_openbox+jwm Permission denied [rocketmouse@archlinux ~]$ sudo -u chuser ls -ld /home/rocketmouse/ /home/rocketmouse/.gtkrc-2.0_openbox+jwm ls: cannot access /home/rocketmouse/.gtkrc-2.0_openbox+jwm: Permission denied drwxr----- 100 rocketmouse rocketmouse 4096 May 15 17:22 /home/rocketmouse/ [rocketmouse@archlinux ~]$ sudo -u chuser cat /home/rocketmouse/.gtkrc-2.0 cat: /home/rocketmouse/.gtkrc-2.0: Permission denied This happens also when logged in as user 1001 (chuser) instead of using sudo -u, take a look at https://bbs.archlinux.de/viewtopic.php?id=27969, it's in German, but that doesn't matter regarding the English terminal output.

[arch-general] Failed building Qt5 with debug symbols

Hello, Trying to build qt5 with debug symbols, but failed. Using the qt5 from abs, per instructions in the wiki ( https://wiki.archlinux.org/index.php/Debug_-_Getting_Traces) I added in the PKGBUILD options=(debug !strip) and added -developer-build -no-warnings-are-errors to the configure and build with and without qt5-webkit.

[arch-general] Panel with weather plugin and editable menu wanted
by Ralf Mardorf 14 May '15

14 May '15

Hi, I like the JWM's panel and I like fbpanel, but they are missing a weather applet. JFTR I tested lxpanel, but already before I checked if the menu is editable, I noticed that lxpanel wakes up external green drives without a good reason [1]. xfce4-panel is nice, doesn't wake up green drives, but suffers also from a menu that isn't editable, neither is the whisker replacement. I suspect mate-panel's menu also suffers from the freedesktop.org menu issue and can't be really customized. Does somebody know a panel with weather plugin and editable menu? A system tray weather app might be ok too. Typhoon and gis-weather seems to be not what I'm looking for, perhaps I'm just to stupid to configure them.

[arch-general] run boinc with optirun but no GPU found
by Stephen Zhang 14 May '15

14 May '15

Hi all, Today I installed boinc, and I'd like to run it with `optirun`. The first time I run `optirun bonic_client --dir /var/lib/boinc`, it showed me that `No usable GPUs found`. So, I installed `opencl-nvidia` package from the repo. After `opencl-nvidia` installed, I restart the boinc with optirun, it showed the same prompt. But after a suspend of my computer, it worked fine! the prompt became like this: ,------ 01-May-2015 11:36:53 [---] CUDA: NVIDIA GPU 0: GeForce GT 620M (driver version unknown, CUDA version 7.0, compute capability 2.1, 1024MB, 1009MB available, 240 GFLOPS peak) 01-May-2015 11:36:53 [---] OpenCL: NVIDIA GPU 0: GeForce GT 620M (driver version 349.16, device version OpenCL 1.1 CUDA, 1024MB, 1009MB available, 240 GFLOPS peak) `------ And a project began to use GPU to caculate as well. However, after I reboot my computer, the boinc can't find GPUs any more! The prompt is always `No usable GPUs found`. I also tried to write a simple CUDA program[1] to test if my CUDA device was ok, and the result was the CUDA program worked fine, it printed 'Hello CUDA!' as expected. My GPU model is NVIDIA GeForce GT 620M as mentioned above. My laptop model is Acer E1-471G 32352G50Mnks. I also have bbswitch installed, and `cat /proc/acpi/bbswitch` shows: ,------ 0000:01:00.0 ON `------ And here is the output of `lsmod |grep nvidia`: ,------ nvidia_uvm 73728 0 nvidia 8409088 1 nvidia_uvm drm 282624 6 i915,drm_kms_helper,nvidia i2c_core 53248 8 drm,i915,i2c_i801,drm_kms_helper,i2c_algo_bit,nvidia,v4l2_common,videodev `------ Anyone knows how I can run boinc with `optirun` correctly, or how I can run boinc with my GPU? Any reply will be appreciated! [1] https://cfp.vim-cn.com/cbSR/c -- Regards, Stephen

[arch-general] Linux kernel 4.0.2-1 flagged out-of date.
by Francis Gerund 14 May '15

14 May '15

Hi. Linux kernel 4.0.2-1 is flagged out-of date, just hours after release. But pacmatic keeps offering it as an update (along with other packages), with no warning message. I am using Linux kernel 4.0.1-1-ARCH (X-64). Should I go ahead and update, or wait for Linux kernel 4.0.3-1?

[arch-general] Why irrelevant updates?
by Francis Gerund 13 May '15

13 May '15

Sometimes pacman presents updates that just don't seem to apply to my system. Just one example: sudo pacman -Syyuv presents btrfs-progs, even though: 1) I do not, and have not, used the Btrfs file system with my Arch setup. 2) It is "Required by: None" 3) It is "Optional for: None" But I hate to reject it. After all, there must be some reason it was presented . . . right? So, if I just say "yes" to all upgrades, won't my system over time get weighed down by excess stuff, until it grinds to a halt? Or, if I just make my best guess at what is really need and reject the rest, won't I have a Frankenstein system that will eventually break? And why, why, why doesn't it just present upgrades appropriate for my system?

[arch-general] fresh install: netctl and interface renaming
by Łukasz Michalski 11 May '15

Hi, I am trying to setup network with netctl on fresh arch install. Netctl fails to start static profile due to different interface name. It looks like netctl is trying to start (twice?) before kernel finishes network interface renaming. What can be wrong?

Switching to the proprietary "nvidia" driver solved the problem. I'm still using the same computer and am now successfully using the "nouveau" driver on Arch, so presumably whatever was causing the problem in 2012 has been fixed.

I've had issues in the past with audio crackles that were caused by the video driver.
