Cannot Start X With radeon Driver Using a 7870.
Catalyst works just fine, but I prefer the open variant for the better 2D performance.
There are no unusual errors in the log. I'm trying to start just with TWM, xclock, and xterm.
When I try to start X as root, it hangs at a black screen instead of crashing.
Weston has a corrupted screen when I try to start it, so I can't use Wayland as an alternative either.
I am using the linux-mainline kernel (3.16 RC7), although I have tried with 3.15.7 as well.
This is on a new install.
Here is the log: http://pastebin.com/RS0cGwwV

Re: Cannot Start X With radeon Driver Using a 7870.
Did you try the other port, DVI-0? Is fglrx blacklisted and radeon loaded and KMS set (it is enabled according to the log)? You have several 'module does not exist' errors in the log.

Yes. I have a CRT connected to it with a VGA adapter. I unplugged it this attempt thinking that would make it work. Same result.
Also, fglrx isn't blacklisted, but I don't have it installed.

Re: Cannot Start X With radeon Driver Using a 7870.
The same thing happens in Debian Sid and Fedora Rawhide (black screen). When I try with Debian stable, Gnome pops up and says that my graphics driver doesn't support running Gnome 3.

Re: Cannot Start X With radeon Driver Using a 7870.
iwasaperson ,
there have been some reports where radeon didn't work with kernel 3.15.x , but did work with 3.14.x .
The cause seemed to be a bios/uefi setting called OSC that's related to powersaving for laptops.
If Debian sid and Fedora Rawhide are also using 3.15.x or later kernels, try linux-lts which is at 3.14.15 now.
Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Thank you. I'll compile it and get back. It's weird because it worked just fine on my 6970 on 3.15.

Re: Cannot Start X With radeon Driver Using a 7870.
no need to compile linux-lts, it's in the official repos.
you'll have to add an entry in your bootloader for linux-lts though.

It works, but only as root, and I have to do a specific set of things to get it to start.
1. Login as regular user
2. Attempt to start X and let it fail
3. Log out and log in as root
4. Attempt to start X with 'exec gnome-shell' in .xinitrc and let it fail
5. Comment out 'exec gnome-shell' and start X again, letting it fail
6. Uncomment 'exec gnome-shell' and start X, and Gnome starts successfully.

Re: Cannot Start X With radeon Driver Using a 7870.
iwasaperson,
those needed actions suggest the problem MIGHT be related to gnome.
Please try starting X with another WM/DE.

When I login as the regular user and it fails, I'm using TWM.
Also, GDM makes the computer boot to a black screen.
EDIT: Lxqt works.
