I recently started using Kanotix, a Debian based distro that loads itself into RAM on boot, and i'm loving it. But this is the second time I have this problem, and I was wondering what caused it and how to fix it.

So it boots up and KDE works perfectly, but for some reason the content of windows freeze up. It kind of looks like you're screen that split second before a BSOD.

Everything inside the window still works, I can still type and everything. When I minimize and restore a window enough times, it will show the actual content.

I can switch between desktops and all effects work perfectly. Restarting the X server doesn't do anything.

Any help will be greatly appreciated.

Sounds vaguely like the driver for your display xard is buggy. Try a different driver and/or a lower resolution. – tripleee Jan 31 '13 at 20:23
I have an Ati Radeon HD5830, and i have the catalyst control center installed. Are there any other possibilities for this card? Because if i remember correctly, i spent hours finding and installing this one... – Petr Safar Jan 31 '13 at 20:56
(1) When it happen, do free and see how much ram is left. (2) How much ram you have? (3) Did you configure swap partition? – John Siu Jan 31 '13 at 21:22
@JohnSiu (1)updated with result of free, (2)I have 8 GB of RAM, (3)I did not manually, but i think that it was done at installation(?) not sure about this, I'm still a bit of a newb at the "behind the scenes" working of Linux/Unix – Petr Safar Jan 31 '13 at 23:54
The symptom match when running out of memory. However you have planty of free ram. I am clueless now. – John Siu Feb 1 '13 at 0:36
