There's an option I think with the script you install it with, or an fglrx-uninstall command possibly. I had to uninstall it from my system and fully re-install all openGL libraries and possibly dri stuff and the X server/drivers. It goes through and alters quite a bit of stuff there and was not easy to get rid of, and with my AVGA 3000 pcie card it never worked and just crashed/locked on trying to start X. Once removed, and having the basic ati driver installed with radeon support, you should be able to do the X -configure command and get a close to working config or at least a start to one. In theory X should be able to startup on a normal monitor without a config at all in /etc/X11 too. Of course once the fglrx stuff has been installed that may be less likely until things are fully restored to how they were beforehand.
Wow! So much to do. I am not experienced with linux but I have learnt a lot over the past year and even use Ubuntu on my main PC now.
I will do a search and see what I can find out.
So it sounds like I need to:
- Uninstall fglrx, which I have already done.
- Install (or re-install) openGL drivers, which I don't think I have done as I am not aware of that.
- Install dri stuff, which I think I have done but will do again.
- Re-install xserver, which I have done a couple of times.
- (Re-)install the ATI driver.
- Configure X.
I'll let you know how I go. If you know what openGL drivers I need please let me know.
