Re: [CentOS] dual heads, Radeon

Dell OptiPlex 980, Radeon HD 4550 xorg figures it should use the r500 driver.

I start with no /etc/X11/xorg.conf. It comes up, mirroring. I use the gnome applet - the same thing, btw, with system-config-display - tell it to use dual head, and spanning desktops. Exit X.

Restart, and the second monitor goes into powersave mode. Try to exit X, either via logout, or <ctrl><alt><bkspace>, and it goes, and comes back with a bluish screen... and that's all she wrote. It's hung so hard I can't log in via ssh, and have to power cycle it.

Any clues?

None other than the obvious - use the proprietary drivers.

Catalyst works well with latest Centos and Fedora.
