my X desktop completly "kinda like suspends" while a away

[yagami]

hi

needing some help..

i am a gentoo user for a long time, dont even usually post on the forums, since i dont remember the last time i needed help.

i am having a weird problem.

sometimes, while i am away ( when sleeping or out ), my computer just suspends the Xorg Desktop.
The base system seems to still be working, the cron hourly scripts keep on running ( as the logs indicate ), but every app that is based on X just "freezes".

Description :

I start emerge on the X desktop terminal at night
i go to sleep
when i wake up in the morning, i see that the emerge just froze for about 1 hour after i left the computer. it immediatly resumes the work when i arrive at the computer.

the same thing goes for internet apps. konversation disconnects an hour after i leave the computer, then , the second i start using the computer again, it reconnects automaticly.

i tried to disable power devil ( kde user ), and other power managers.

it seems that if i completly disable monitor dpms it doesnt happen, but i dont want my monitor always on.

i started noticing this for a month now. really completly lost and in need of help

Kernel -> 2.6.35
Xorg -> 1.8.2
Desktop -> KDE and Gnome installed , running KDE

thanks

Chances are you can either set your monitor's power monitoring either on the monitor itself or through your machine's BIOS. Check for those and use those if they're available. It'll free up your system for other things.

[yagami]

well , i really doubt its the bios. there doesnt seem to be any option there regarding this problem.

also , this problem really doesnt always happen.

latelly its been happening less and less , but still does

[yagami]

just happened again today.

i am at work, and i see that my irc konversation nick just went offline.

funny thing is that i then try to login to my machine by ssh , and it works.

the machine is running , but everything related to X is "frozen".

if i do a DISPLAY=:0 and then a xset q , it doesnt do anything , xset just seems to be frozen.

really , really help !!??

if i cant sort this out , got to change to another distro , and i really dont want to leave gentoo.

thanks

[yagami]

?? help ??

What a strange problem! Certainly emerge is running it its own process so it is not like one slowpoke is blocking a single execution thread. It is more like the X server has gone to sleep and everybody is stalled waiting for it to process their requests.

Would it be difficult for you to revert to the stable version of the X server?

What about your graphics driver? Can you try a different version?

[yagami]

well , it would not be dificult to revert into a older version of X ...

but i have changed so many packages since then, i really dunno

it really seems , that with monitor with dpms off , this problem doesnt happens. i could almost say its a dpms problem

[Ant P.]

This is a known problem in the intel drivers (assuming you use that since you didn't specify); newer versions (>2.10) have fixed it.

[yagami]

[yagami]

well , i think this issue is solved.

i downgraded alot of Xorg packages to stable.

i will try to see if the problem is really the xorg-server pkg , since my desktop is kinda messy right now , i need at least a more updated mesa package.

thanks for all the help ! really glad this was fixed thanx alot really

The latest ain't always the greatest!

[yagami]

heh true

but in my case ... only the latest mesa works without flickering all the time on my video card.

i am gonna try to install just the mesa pkg and nothing else.

[yagami]

well , it started happening again after i updated some packages :

eselect-mesa
mesa
libdrm
libX11

from x11 repository

so .... i guess the problem is in there. gonna try to downgrade those packages and see if the problem is gone again

[yagami]

Finally , i think i solved this problem.


Its due to .... wont believe it but true .... VSYNC disabled.

if i enable VSYNC , this bug doesnt happen !!!

weird
