I previously said it was working in 12.04, but that was because it was using the VESA driver and not radeon. I did try the latest snapshot of tasty 14.04 and xorg started without issues, so this bug can be closed.
I also found the following which is the exact same bug: https://bugs.freedesktop.org/show_bug.cgi?id=68984 'Looks like your X server loads the "glx" module ahead of time by default, which is known to break glamor.' ** Bug watch added: freedesktop.org Bugzilla #68984 https://bugs.freedesktop.org/show_bug.cgi?id=68984 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1259049 Title: Xorg segmentation fault with AMD HD 7790 Status in “xserver-xorg-video-ati” package in Ubuntu: New Bug description: I'm trying Xubuntu 13.10 64-bit. I booted up the live disc and selected 'Try', and got a blank screen. I looked at the logs and I'm getting a segmentation fault in my Xorg.0.log file with the radeon_drv.so module. I've attached the full Xorg.0.log file. I've also pasted the important part below. I was previously using 12.04 and it was working without issues. My video card is ASUS HD 7790 DirectCU II.
