[gentoo-user] Restart "frozen" X

[gentoo-user] Restart "frozen" X

[Joseph]

I'm running Nvidia driver: 310.32 with my GeForce GTS 450 kernle-3.1.6

but I've noticed it freezes my screen once a day or ever second day.
Mouse is moving but no icon is responding, nor can I use the keyboard (all frozen).

I can login to the system over ssh.  I've tried to restart/zap "xdm" it doesn't help.
What else can I do to restart "X"?

You can try killing the process named /usr/bin/X. I was in a similar
situation once and this worked, don't know how safe it is.

You can use the SysRq Key (I use <Ctrl><Alt><PrtSc>)
and then RE

You might have a look at http://en.wikipedia.org/wiki/Magic_SysRq_key

R is okay, this resets the keyboard, and often helped me in the past to 
get my keyboard back.

But E would kills all processes except init. Use K instead, this only 
kills processes on the current virtual console.

I suppose Ctrl+Alt+Backspace doesn't work? (With X having locked up and 
everything.)

I've tried key combination <Ctrl><Alt><PrtSc> doesn't work nor does <Ctrl><Alt><Backspace>
besides when it is frozen keyboard is not responding, I can not even do:  <Ctrl><Alt><F1>

I'll try to kill next time: /usr/bin/X
as Yohan suggested, I did it on my backup computer and X just restarted.

If downgrading nvidia-drivers doesn't help check your power supply. My
computer exhibited this issue a while back because the voltages went all
wonky and the hardware really didn't like it - I could still ssh in from
my tablet but the entire computer appeared frozen.

If I just ran at the console (ie not starting X) the computer would work
fine all day.

I don't know what nvidia card you have but mine requires two extra power
connectors but the PSU just couldn't supply enough power to keep the GPU
stable.

Hi,

I have had that same behaviour for some months now, but wasn't able to find
the cause. I am now suspicious of one of the browsers (I use Firefox and
Chrome, and always kept them opened), because all I could get was a kernel
log message referring to browser traffic (?) prior to one of those freezes.
For a few days now,  I always close the browsers, and have had no freeze.

Good luck, and please keep us updated.
Francisco

I have a: GeForce GTS 450
It was flawless until recent upgrade; I don't suspect power supply.
It only freeze on me two times and right after upgrade; the last time was when I hit a link in thunder-bird email client but I think it has happen when I open a link in 
firefox as well (don't remember).
I'll keep monitoring it.  I did not upgrade the kernel only the nvidia driver.
