Post subject: corrupted kde graphics
Hi, I installed Aptosid on a computer that my dad does not use anymore. For some reason, the menus in the application launcher and panel would sometimes glitch up and I cannot see the text and colors would also change. I have done DUs correctly and I have pretty much changed nothing in terms of configurations. I have no idea of what is going on. Can anyone assist me? The computer is an HP a1010n if it helps to know.

Sorry if I have too many screenshots.

I just started seeing this today myself

What video card are you using ?

I am using nvidia, I am out food shopping and will check this out later

I am using Intel's integrated graphics, the i845 I believe.

I have also had two times where the screen go blank on me for a second or two as well but turns back on. I don't know if this is related.

You may try system settings -> workspace appear -> Desktop theme

choose a different theme (i.e oxygen or Air) and report what happens).

Changing the theme didn't help unfortunately... even the windows gets messed up.

The graphics doesn't look like piper's though.

Your 2nd+3rd screenshots look like what happened back in April to my Intel graphics (82915G) machine of similar vintage, although I use Fluxbox not KDE:

Scroll down to my second post for a screenshot (Right-click to View Image full size) to see similar symptoms like missing text. I never found out the cause but luckily it stopped happening a while later, probably fixed upstream. Sorry I can't offer much real help, but have you checked the logs for weird errors? (increase the number 100 for more messages, and Google any suspicious errors)
tail -n 100 /var/log/Xorg.0.log

...or more importantly, check the size of logs; my /var partition got flooded with massive fast-growing log files when that bug hit me.
ls -Sshr /var/log/

FWIW, I very occasionally see some similar problems too in KDE.

Have you upgraded your kernel (I'm not sure about the default kernel upgrade behavior in the latest Aptosid)? That may bring in an upgraded video driver. You could also try resetting KDE to defaults:
Ctrl-Alt-F1 and log in as root
# service kdm stop
# mv /home/{your_username_here}/.kde .kde.bak
# service kdm start && exit

So I copied what Luis did and ran the same command. Smile
Side Thought: I saw "ht" as one of the flags, any chance I can use HT? XD

I also opened my logs and saw that there was this message:


[   102.181] (EE) intel(0): Detected a hung GPU, disabling acceleration.
[   102.181] (EE) intel(0): When reporting this, please include i915_error_state from debugfs and the full dmesg.

I tried to post the relevant logs. I don't mean to impose my responsibility on anyone, its just that I don't really know what I am looking for. Sad
I have also noticed that the computer has been freezing up completely sometimes under KDE, especially when i first turn it on. For some reason though, when I boot into LXDE environment, I do not experience any problems. O_o

ht := hyperthreading is used automatically, if the hardware allows it (your system does not use it). There are two requirements for HT:
- the CPU needs to have ht support, yours does.
- the mainboard (==BIOS) needs to enable it, especially early p4 mainboards (notebooks in particular) often disabled it on default and sometimes didn't even offer a knob to enable it in their BIOS.

You may want to check for messages other than "no error state collected" in i915_error_state:
# mount -t debugfs debugfs /sys/kernel/debug
# cat /sys/kernel/debug/dri/0/i915_error_state

I redirected the cat results into a file.

I don't know what other files are important, I only posted the dmesg, Xorg.0.log and the i915_error_state log so far.

Looks like i915 driver issues in combination with your Intel 845G integrated graphics chipset. You could try turning off desktop effects in KDE, changing your font anti-aliasing settings or add a PCI video card. When you get a system freeze, is it really complete or can you still get to a console with Ctrl-Alt-F1 or get back to a log-in with Ctrl-Alt-PrtScreen-k?

It's completely frozen.

What is also weird is that when I login into the desktop and not move the mouse after its done loading up everything, that is when it freezes. When I move the mouse, the desktop doesn't tend to freeze up, not to say that it won't freeze up later.

A complete freeze is bad. I'm wondering if you may have a hardware issue. I've been using the Intel i915 open source driver with the H3000 graphics in the core i5-2500k CPU for a few months and the worst I've had are a few X crashes, taking me back to the KDM login. You may want to check your RAM with memtest86+ and hard drive with Gsmartcontrol, for starters. You can also file a bug on the Intel driver.
