When I am working only on integrated LCD (1024x600x60) - everything is OK.
When I connect d-sub to my old CRT monitor (Philips Brilliance 109P, 
1280x960x85, internal laptop LCD off) for some time is almost OK (sometimes 
screen flickers - in Xorg.0.log driver again recognise monitor ModeLines).
After some time, especially when I start movie in Totem or SMPlayer, screen 
disappears (sound works, everything works, but no display on CRT - all screen 
filled with one colour) - driver is starting filling Xorg.0.log with many "(EE) 
intel(0): underrun on pipe A!
".

I could switch to terminal (Ctrl+Alt+F1) - display works again on LCD
and CRT. If I back to X (Ctrl+Alt+F7) - still no display. I could
restart laptop or start another X session (xinit -- :1) - works again
OK...

I changed d-sub cable, problem still remains, but I have little
impression that is happening less often... Maybe driver is
sending/receiving too weak signal to/from monitor?
