[karmic] suspend to ram broken in kubuntu

[Jithin Emmanuel]

Binary package hint: xserver-xorg

After my laptop wakes up from sleep its has a desktop unusable.

The place where plasma used to be is blank. But right clicking on it shows the context menu, but nothing is displayed there. Only thing I can do is restart or log out.

Please take a look at the picture. Windows have lost the border and in bottom place plasma is missing.

Upto 2.6.31-6 kernel suspend to ram used to work. I noticed this regression after that.

[Jithin Emmanuel (jithin1987)]

I am seeing one more behavior. If the system is in sleep for more that say half an hour, then when waking it up the kdm login screen does not even appear. Its pure black. But if I enter my password based on an assumption, it seems to be working then when I move my cursor it changes when it passes my notes in desktop. But at this point I cannot even log out. Only thing I can do is do a VT switch and reboot.

Hi jithin1987,

Thanks for including an image to demonstrate the issue. Could you also please attach the output of `lspci -vvnn` and `dmesg`, and attach your /var/log/Xorg.0.log or Xorg.0.log.old file from after reproducing this issue. If you've using a custom /etc/X11/xorg.conf please attach that as well.

The behavior is changing. This time its more like comment 3.I am only getting the black screen. I did a VT switch and changed back. At this point it completely froze. Only sysrq RSEIUB was working. After this I ssh'ed from another host and took he xorg logs.

After this my system refuses to boot in the first try. It says fsck failed as super block write time is in future. and asks to run fsck manually. I have been noticing this fsck for a long time, when ever I have to uses sysreq keys because of this issue.

With desktop effects disabled, I am not having this issue. Something is going wrong with xserver with desktop effects enabled.

I am signing up to this bug as it affects me

[zoomy942 (zoomy942)]

here is something similar

[Travis Watkins (amaranth)]

When you say desktop effects do you mean compiz or kwin effects?

[Jithin Emmanuel (jithin1987)]

I meant the kwin effects. The ubuntu people does not even know kubuntu has kwin effects not compiz ;)

[zoomy942 (zoomy942)]

Compiz here buddy.

I have a similar situation as described here: http://ubuntuforums.org/showthread.php?t=1252138
However, the system doesn't even let me log out/switch to TTY. So the only solution is to hard-reset.

An interesting thing. If I switch to TTY1 and run a manual

sudo pm-suspend

I am able to reinitiate in TTY1 after suspension (even though it spits a few errors... does someone know how to save/copy the terminal output to show here?). However if I switch back to gdm (ctrl+alt+f7) everything gets frozen again.

On the other hand. If I suspend/proceed through TTY1 as described above and then restart the gdm with

sudo /etc/init.d/gdm stop; sudo /etc/init.d/gdm stop;

it works OK. But you have to re-login afterwards and everything you had open in your lasst session is gone (clearly, not what suspension is meant to be :P)

[neferty (roman-semko)]

hmmm killing compiz did the trick, too. It acts strange lately. The screen gets frozen from time to time (especially, when using alt+tab program switching) and compiz.real goes up 100% in CPU usage.

[Timo Jyrinki (timo-jyrinki)]

I can confirm problematic composition manager on resumal using normal Ubuntu.

For me, the screen seems to be hung. Problem can be solved by blindly typing alt-f2 and metacity --replace or even compiz --replace. Not using compiz seems to solve the issue as well, but also restarting compiz seems to always work as well.

[neferty (roman-semko)]

by turning compiz off completely seems to fix the problem and suspend works flawlessly

[zoomy942 (zoomy942)]

Thats correct. You can also just go to Appearances and disable the desktop effect and re-enable them

[neferty (roman-semko)]

hmm. if I re-enable them I keep getting the suspend issue again

What i meant to say was, once i go into suspend (with compiz enabled) and i wake my Tablet PC, those title bars are gone, but if i go into appearnce and disable desktop effects and re-enable them, it will put the title bars back - until i suspend again.

[Pedro Francisco (pedrogfrancisco)]

I'd say this is a GM965 exclusive issue. On KDE disabling Desktop Effects also workarounds the issue.

[Travis Watkins (amaranth)]

This affects all windows with RGBA visuals, that is why only some windows seem to disappear. With compiz the decorations go invisible since they are translucent and a separate window and if you have gnome-terminal set to be translucent it'll be invisible too. That's why people are losing the plasma dock thing too, it is translucent.

good to know Travis. Is there anything more we can do to help you?
