kde-3.5 crashes on shutdown... kernel problem?

Message

Hi all

I have an intermittent problem when I shutdown kde. The screen goes black, and the mouse pointer freezes. Nothing works other than switching off the power (not even Ctrl-Alt-Backspace, or Ctrl-f2).

My hdd performance also seems adversely affected. If I build (emerge) something large while in a terminal window, performance eventually degrades until the machine is unuseable. CPU usage is fine, but if I run "hdparm -tT /dev/hda" the cached reads performance drops to about 1/4 of what it should be. When this happens, I can pretty much guarantee that kde will hang when shutting down.

This only seems to happen when I boot with (kernel) 2.6.16. If I roll back to 2.6.15, the problem appears to go away.

Does anyone know of any recent changes in the kernel that might effect kde and/or xorg (6.8.2-r7)?

Thanks in advance for any help.

No, sorry, should have mentioned. Running a Dell Inspiron 700m laptop. Standard built-in intel graphics I think.

I'm having the exact same problem. But my video card is an ATI radeon 200M, on a HP Pavilion zv6000 laptop. I'm running KDE 5.2 and the kernel version is 2.6.17-gentoo-r8.

The mouse keeps working in a black screen. No keyboard input is accepted. CTRL+ALT+BACKSPACE doesn't work, neither ALT+F1, ALT+F2.

Is there another way to kill the X server without powering off the computer?

this is ati-drivers well-know problem. It exists for 1 year already.
Use opensource driver.

I think I figured out when I reemerged my ati-drivers. I can't remember exactly what the message says, but I did the following:

In the video card Device section on your xorg.conf, you should have the option UseFastTLS set to 0 or 1, but never to 2. In my config it is:

Code: Select all

Section "Device"
        Identifier  "ATI Technologies, Inc. Radeon Xpress 200M (RS480)"
        Driver      "fglrx"
        ...        
        Option      "UseFastTLS"  "1"
EndSection

I haven't seen this problem after I did that.
