Laptop display panel randomly shuts off while playing Dolphin.

Hello everyone,

I'm running Dolphin 4.0-0 (64-bit) on Ubuntu 13.10 on an Acer Aspire 5920 laptop. Most of the time, games play fine (well, if you consider 50% to 75% speed to be okay). But every once in a while, while playing a game, my screen will just turn off with no warning at all. Just poof! And I can't use the Fn+F6 key to turn it back on like I usually can. This forces me to hold the power button and hard-reset the computer, because I can't see anything on the screen at all. I also tried Dolphin 3.5 and got the same exact issue. I have tried the 32-bit Windows version both natively on 32-bit Vista (dual boot) and by using WINE, and no such thing happens. Is it a faulty OpenGL driver? What gives?

maybe an overheating issue with the GPU? You didn't exactly give a lot for me to go off of.

I don't think my GPU is overheating, though. The hottest my laptop ever gets is around 65 degrees C, according to the 'acpi -V' command. I'm not sure, but I think my computer has Intel integrated graphics (ugh :p), so if the GPU overheats, so will the CPU. How do I go about diagnosing this problem?

GPU-Z should tell you your GPU temps.

GPU-Z is Windows only and doesn't run in WINE. From the /var/log/kernel.log file, I see a bunch of lines about Graphics card errors, so I think it's a driver problem. Pokemon Colosseum doesn't seem to have this problem, and it's about the only game that runs at a decent playable speed on this old computer, so I'll just not worry about the others.

Can you post the errors?

What driver and version are you using? lspci -k

Sounds like you're using a gamepad and your screensaver kicks on and then causes issues once the screen turns off.
Dolphin is supposed to disable the screensaver, but it is probably encountering some form of an issue.
