I booted a few minutes ago and everything was fine, update manager notified me about new updates so I decided to install them, and then poof, dim/dark screen is back in action.
I did update grub, I did tried to remve fglrx but terminal said I don't even have it installed and the "classical" fix I used is the
sudo setpci -s 00:02.0 F4.B=01
It does work, but only till I reboot, I had same problem but I added this code before exit 0 from /etc/rc.local [
gksudo gedit /etc/rc.local] now it's still here but it doesn't work. I also tried nomode set before booting, it resulted in a crash.
Any ideas how to fix it? And I would also want to know if I can get completely the rid of this thing? It always came back when the computer was idle or when I tried to run things in full screen mode.
Other info: I run it on an Acer Aspire 5732Z with Intel GMA 4500M (graphics accelerator) if this helps.
