Disable screensaver, power management on Linux
0%
Description
What steps will reproduce the problem?
- Play game (on Linux) for X minutes until screensaver/power management kicks in
- Watch game disappear :-(
What is the expected output? What do you see instead?
Screen savers and display power management functionality should be disabled while a game is running. Rationale is that you don't want you game interrupted by a screen saver covering the image or the monitor powering down.
Previous issues relating to this: bug 2568, bug 2315, bug 1084, bug 203
On current Linux builds, this functionality does not seem to be implemented. Every 10 minutes while I'm playing a game, my monitor enters sleep mode and powers down. This occurs whether I'm running in windowed or full-screen mode.
Previous discussion and code seems to focus on Windows support, so I'm not sure if this is a regression on Linux or just if it's never been implemented.
Dolphin version with the problem? Other Dolphin version without the
problem?
r6239 fails. I'm new to Dolphin, so I've not seen it work.
32-bit or 64-bit and any other build parameters?
amd64. Build options:
scons -j 7 opencl=true shared_glew=true shared_lzo=true shared_sdl=true shared_zlib=true shared_sfml=false shared_soil=false verbose=false
OS version and versions of tools/libraries used?
Gentoo amd64, GCC 4.4.3, wxGTK 2.8.10, KDE 4.4.5
Please provide any additional information below.
This definitely occurs for power management. I'll check tonight to verify whether it's an issue with screen savers as well.

I don't think power management is disabled in the Windows build either.

FYI, I've confirmed that screen savers are indeed not disabled either on Linux.

I found a possibly easy solution. I did some digging into how various media players disable screensavers and and power management and found the Xine and VLC have both switched to using xdg-screensaver to handle it rather than their own code. xdg-screensaver is part of the xdg-utils package, which includes utilities for handling various desktop and window management functions through a common interface.
The rationale, of course, is to leverage another utility specifically written for this purpose rather than trying to custom write and maintain a solution yourself. Based on some brief research this doesn't seem to be a perfect solution - there are some edge cases where xdg-screensaver doesn't work, as well as some bugs in the program that have been fixed only in CVS - but it looks like it should handle the majority usage scenarios just fine, and should be relatively easy to implement.
I tested this on my own system by manually running "xdg-screensaver suspend 0x02e00154" (the Dolphin WindowID) while playing a game, and it did indeed temporarily disable both my screensaver and power management settings.
For anyone interested in looking into this, here's some info about the utility:
http://portland.freedesktop.org/xdg-utils-1.0/xdg-screensaver.html
and here's how VLC uses it:

I vote for this bug :)
It's real annoying to have the power management stuff kick in in the middle of the action, and it's more annoying that you have to disable it before gaming... just to forget re-enabling it once you exit.
The xdg-screensaver is a neat trick too, and since even my ancient FC6 has it, it would be nice to have it implemented. In the meanwhile, we could survive with some shell-fu magic.

This issue happens for me with the last Dolphin (built from the master branch). I use it with KDE on ArchLinux. After a few minutes, when the power management is on, it dims the screen then shuts it off.

I have the same issue, also on KDE, but Debian linux bookworm. My CMake config is attached as image. Else just default compiling:
cmake ..
make -j12
