I've been trying get the fglrx driver running on my custom 2.6.21 and after all the googling and breaking my head, I'm still unable to get it going.
To begin with, I intalled the driver using yum and it goes fine, but the only problem is that I cannot use my custom 2.6.21 kernel. I then cleaned it up to reinstall for my custom kernel. For this I got the driver from ATI and tried two approaches both of which failed in the same place(aticonfig: munmap_chunk()), which is same as above
1. Using ATI's install GUI
2. I built the RPM and try to install them.
Also, another thing I meant to add was does it work if you use aticonfig instead of amdcccle? Either setting up dual head or Big Desktop? You could also try the aticonfig Dynamic Display Management Options. aticonfig --query-monitor
I had to reinstall my system last week, and the display is now in a funny mode I can't seem to change.
I have a Y-connector from the analog output of the graphics card going into the analog inputs of two monitors.
The mouse travels across both displays, but each desktop is independent - I can't drag windows from one desktop to the other. It's not in "clone" mode, but it's not in "Big Desktop" either. I would like to get "Big Desktop" mode working again, but any changes I make to xorg.conf seem to lock up the system. Running amdcccle has no effect - the program doesn't modify xorg.conf, even though the permissions are opened up.
If I use system-config-display, the resulting xorg.conf file causes the system to lock up when I restart the X server.
Here are my details:
OS - RHEL4
Card - Radeon X600
Driver Version - 8.36.5
Catalyst Control Version - 0.9
Any light that someone can shed on this would be appreciated.
