Trisquel lags when playing videos and video games, sometimes freezes
- Inicie sesión o regístrese para enviar comentarios
Recently Trisquel starts lagging when I play videos and video games. Sometimes Trisquel freezes completely. When Trisquel freezes, the video pauses but the audio loops over and over again. I have to manually restart the computer whenever this happens.
How can I fix this problem? Do I need to change my video card or other hardware? Do I need to upgrade anything?

Linux-libre's radeon driver is far from being complete. In particular, there is no 3D acceleration. Do you have an AMD CPU too? If it is Intel, you had better remove the video card and use Intel's integrated graphical chipset: better support and performances; less memory consumption!

In addition, your hardware might not be able to reproduce
high-definition videos and games at high resolution. My laptop has Intel
GPU and 3d support, but still it is not able to playback above 720x
videos. My last desktop computer had an AMD video card without 3D
acceleration and also unable to reproduce clips above 720x.
Normally my computer can run 720p and 1080p videos quite well. I have never had this problem with Trisquel before. The symptoms have appeared only recently. Do you think this problem is caused by old hardware?

Test another player? For example mplayer, vlc, totem, xine. Are those
videos local or accessed over a network? Slow network connection can
cause the problem you describe.
> My computer has an Intel CPU.
The assumption is that you have Intel GPU as well which should have
free software 3D support.
> Do you think this problem is caused by old hardware?
Shouldn't be if you were able to reproduce 720p and 1080p.
The videos are local.
The computer freezes sometimes when I use Totem and SMplayer. I haven't tested other players though.
>The symptoms have appeared only recently.
Check the updates you've lately installed, especially look for kernel (linux-image) and xserver related.
You can find the logs in /var/log/dpkg.something
The software that I've installed recently, as far as I can remember, are i2p and VirtualBox. I don't think they have anything to do with this problem.
I read /var/log/dpkg.log. I found this line, but I don't think it's relevant to the problem.
2013-12-01 13:47:41 status installed linux-generic 3.2.0.56.66+6.0trisquel2
I didn't find anything related to 'xserver' or 'linux-image'.
That's a new kernel and could be related. You could try the new Linux-libre kernels from e.g. http://jxself.org/linux-libre/
uname -r will show you what kernel you're running now. Holding shift at boot should show you the grub menu where you can select which kernel you want to boot. I believe the latest is the default. (or perhaps whichever latest installed)
ps. virtualbox is going away in Trisquel 7 so you might want to look at the alternatives.
uname -r
3.2.0-57-generic
My computer has an Intel CPU.
When that happens, try Ctrl+Alt+F1. If that switches to a terminal session (where you can log in), then the kernel is not panicking. From the terminal session you can kill the problematic processes or even the whole graphical session with 'sudo service gdm restart'.
To fix the actual problem, you should first understand it: read the logs (in /var/log) of what happened just before a crash.
It may also be a hardware issue: I would check the RAM with memtest86+ (in Trisquel's repository and to run from GRUB's menu).
I suspect you do not have 3D acceleration.
Could you post the output of
glxinfo | grep OpenGL

The glxinfo command is provided by the mesa-utils package.
glxinfo | grep OpenGL
OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x300)
OpenGL version string: 2.1 Mesa 8.0.4
OpenGL shading language version string: 1.20
OpenGL extensions:
You are currently running the Mesa Software Renderer for 3D which makes playing games with 3D (like Tux Racer, Open Arena, etc) very slow.
I can not comment on your desktop experience but for 3D you will most likely not be able to play any 3D games on Trisquel. Pure software based renderer and video playback on the other hand rely on good acceleration extensions of your x-Server.
If you are running pure Vesa things turn out to be slow. You can check your Xorg.0.log to find out which Xserver you are running.
Running a desktop on pure Vesa really sucks. I had the same experience with the Atom-based PC I build for my daughter which had the cumbersome PowerVR-based GPU integrated. Even very small resolution videos could not play back without visual corruption :(

Also the vendor string (VMWare Inc.) suggests that this is a virtual
machine, which means that your video card is emulated in
software. Running in a virtual machine will explain why you are having
problems. Probably there are not enough resources (RAM, CPU) to
emulate the virtual machine and playback the video at the same time.
VMWare is not free software. The free software vitalization programs
VirtualBox and Qemu are really good and you can use them
instead. VirtualBox has the ability to provide 3d acceleration to the
guest OS, but I've never used it. I think you can even run VMWare
images inside VirtualBox and Qemu.

Good to know. Thanks!
The vendor string itself does not indicate that he is running a VM and his video card is emulated but that lvmpipe (= the software OpenGL implementation of Mesa) is running.
See here:
http://www.mesa3d.org/llvmpipe.html
I do not remember the exact details but AFAIK VMWare provided some code to the Mesa project as part of the guest 3D extension for Linux VMs.
I am not running Trisquel on a virtual machine.

Sorry, my mistake. The VMWare vendor string fooled me. As others have
pointed out, that string does not (necessary) mean an emulated card as
I expected.
@spyfall: It might be useful if you post your system specs in order to nail the your source of problem.
For lacking 3D support the issue is simple: All ATI/AMD based cards rely on non-free ucode / BIOS files to enable 3D via radeon driver. This is not supported by Trisquel.
