Details

Description:
Hard to describe… It seems that fonts don’t get displayed. Seeing the screenshot, I’m not sure it is the only problem, though…
Linux console is OK. E17 is OK.

Additional info:
* current (working kernel): 3.9.9-1
* tested non-working kernels: 3.10.2-1 and 3.10.3-1

Steps to reproduce:
* upgrade kernel,
* get this: [attached screenshot]

As you can see, Enlightenment17 has no problem for some reason. However, all other applications I tried were displayed like the screenshot: Firefox, Thunderbird, Geany… and SLIM (the display manager)!

On the login screen for example, I can enter my login name, but nothing is shown on screen; it lets me login though.

Downgrading Kernel to v3.9.9-1 doesnt solve the issue for me...

EDIT: Ah, sorry! Downgrading to kernel 3.9.9 does solve the issue! SDDM (my login manager) still flickers but this seems to be Qt5 related. Ignore my previous comment!

This patch by Alex Deucher fixed it for me (I applied it to 3.10.7 Arch source package); I have an HD 4770 and am running on x64.

I have attached Alex’ patch, my PKGBUILD patch and a patched PKGBUILD for convenience.

The patch has been merged upstream. v3.11-rc7 will contain this fix.

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d2b2c08456d12a9914c87cef479b2ec2ab30337f

It's not yet in stable though.
