11.2 - strange problems with graphics

I have strange problems with graphical interface - programs are randomly having problems, sometimes X restarting. For example, I tried to watch movie in vlc

:~> vlc
VLC media player 1.0.3 Goldeneye
[0x804f3a8] main libvlc: Running vlc with the default interface. Use ‘cvlc’ to use vlc without interface.

Blender not always correctly opening file, sometimes colorful squares or lines are visible through all screen, either first or second blender screen. X randomly crashes some times in a day, redirecting to login screen, also I couldn’t start all games (not with wine, linux games). In short - strange problems, and I’m not sure about their origin :\ I just guessing, that this is because of nvidia 190.14 driver installed (at least nvidia-config showing that), but just guesssing. Video card is GF 6200, if this matter. DE is KDE4. If you need any more info I’ll provide you, just ask.

For example I just tried to launch tvtime, after trying to get it full screen it simply disappeared. From .xsession-errors:

Running tvtime 1.0.2.
Reading configuration from /etc/tvtime/tvtime.xml
Reading configuration from /home/senis/.tvtime/tvtime.xml

Cannot allocate enough off-screen video memory.  This may be fixed by:

  **1. Closing or restarting large X applications.
  2. Lowering the input width of tvtime (--inputwidth parameter).
  3. Lowering your colour depth or highest configured resolution.
  4. Increasing the amount of video memory in your X config file**
     (for example, if you are using the i810 XFree86 driver.)

See http://tvtime.net/ for more information.

Thank you for using tvtime.

Where the problem could be? This is annoying :frowning:
