Killing compsitors (Compton)

Instead of

killall compton && %command%; nohup compton &


killall compton; %command%; nohup compton &

be better as it does not rely on compton running when you start up a game? I've been frustrated more than a few times when I'd start a game, forgetting that compton wasn't running and the steam game would hang. —This unsigned comment is by Wartz (talk) 15:38, 9 March 2015‎.

I think both are terrible. The proper way would be to to read the compton manual and adjust the configuration accordingly (i.e unredir-if-possible = true). But if you did use a command like this, know that compton has a -b switch to daemonize, making nohup redundant. -- Alad (talk) 14:58, 9 March 2015 (UTC)
Thanks for pointing me in that direction. unredir-if-possible seems to work fine with fullscreen games instead of outright killing the compositor. I'm not sure how much of an effect the compositor has on windowed games though. Wartz (talk) 17:30, 9 March 2015 (UTC)

Hardware decoding for In-Home Streaming

For Intel Graphics


For NVIDIA Graphics

First, make sure that lib32-libva-vdpau-driver is installed from the AUR. Then, move the old steam vdpau folder out of the way:

mv ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/vdpau/ ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/vdpau.bak

Then, link in the vdpau folder from your system:

ln -s /usr/lib32/vdpau ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/.

To prove to yourself that it's working properly, make sure you have "Display performance information" ticked in your steam settings on the client under In-Home Streaming/Advanced Client Options. Now when you start streaming, press F6 on the client. The "Decoder:" line should show "VDPAU hardware decoding"

An update of the steam-runtime will likely overwrite these changes. Greyltc (talk) 12:29, 15 April 2015 (UTC)

How to read Minidumps?

Set up Steam and have been playing around with a runtimeless install. It seems to work okay sometimes, other times it seems to randomly crash, giving minidumps that sit in /tmp. I'm familiar with using gdb to backtrace coredumps but these minidumps are something else, and I'm having a hard time finding out how to actually use them to figure out what's going on. Anyone have any clues? If so, that's perhaps something to add to this page. Insidious611 (talk) 16:10, 28 April 2016 (UTC)
