During the week I did a update through the update manager and since then my desktop graphics have stopped working properly.
I usually just quickly glance through the list of packages to be updated before pressing install and this time I notice that a component called fglrx was going to be updated. I can only speculate that this has anything to do with it. I chose to update...
After the update I did a reboot and that's when the trouble began. My system was unable to boot into high resolution mode and gave me the option to boot into low graphics mode or reconfigure. I tried the reconfigure option but it didn't do anything and after I fiddled around a bit I was able to get back to a low-res desktop.
The first thing I tried was
sudo dpkg-reconfigure xserver-xorg but this seem to do nothing. It just dropped me back to the command-line without a message.
Then I checked if my hardware drivers where still enabled so I opened System / Administration / Hardware Drivers panel and after searching for available drivers it came up with an empty list. I decided to downloaded the latest ATI x86_64 drivers and did an install of those. Installation was successful and I did a reboot.
I'm currently in high-res mode but I don't seem to have any hardware acceleration. Dragging a window around the desktop is a painful process to watch. There is an
aticonfig command line utility that outputs about 50 zillion options. I'm pretty sure there used to be a graphical UI version of it but I can't seem to find it anywhere in my Applications menu.
When I issue the following command:
fglrxinfo I get the following output:
X Error of failed request: BadRequest (invalid request code or no such operation) Major opcode of failed request: 136 (GLX) Minor opcode of failed request: 19 (X_GLXQueryServerString) Serial number of failed request: 15 Current serial number in output stream: 15
I'm on Ubuntu 9.10 and I have an ATI Radeon 5450 video card.
Any help would be greatly appreciated.
