After realizing that all my old repositories for 11.2 had gone missing, I decided to upgrade to 11.4. I had been using fglrx in 11.2 and it had worked fine. I started having problems in 11.4 though.
I’ll admit that I tried a few times to install fglrx, in a couple different ways, and every time it had horrible performance in one way or another, and every time I couldn’t figure out how to remove it without making the system go to command line at reboot. I’m not even vaguely comfortable using a command line interface unless I have specific instructions, so I reinstalled 11.4. Several times.
I tried activating radeonhd as well.
In both radeonhd and fglrx (worse in fglrx) I had problems with scaling video and shearing. A couple times, installing fglrx from a file, my cursor disappeared. Since one of the main things I use my computer for is watching fullscreen videos, scaling is absolutely important. The radeon driver seems to function a lot better with scaling video, and other performance, but my card is not technically supposed to be one of the ones it supports. Also, every 20-30 seconds or so, the screen flickers to black and back again, which is not even vaguely acceptable.
I have a ATI Radeon HD 3650 AGP card, and I use a converter to run a CRT monitor on it.
So my question is this: has anyone had a similar experience, and if so, what would you recommend? Is there a way to make radeonhd or fglrx work better, or to stop the flickering with the radeon driver? Any help would be appreciated.
