Issue with radeon driver

Hello,

I've got an hybrid ATI/Intel Lapotp which was working fine until one day.

[dalexandre@Ohara ~]$ lspci | grep -e VGA -e Display
00:02.0 VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09)
05:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Opal XT [Radeon R7 M265] (rev ff)

Now, I'm not able to use an external monitor with a decent resolution. I think the issue is coming from the radeon driver who is not working as it should.
The first weird think is it doesn't appear with xrandr even though the radeon module is loaded

[dalexandre@Ohara ~]$ lsmod | grep radeon
radeon               1482752  2
ttm                    77824  1 radeon
drm_kms_helper        102400  2 i915,radeon
drm                   286720  12 ttm,i915,drm_kms_helper,radeon
i2c_algo_bit           16384  2 i915,radeon

[dalexandre@Ohara ~]$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x49 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 6 associated providers: 0 name:Intel

Finally, I've this message at boot concerning the radeon driver

[dalexandre@Ohara ~]$ journalctl -b | grep radeon
déc. 04 19:03:28 Ohara kernel: radeon 0000:05:00.0: VCE init error (-110).
[…]
déc. 04 19:03:29 Ohara kernel: [drm:radeon_pm_late_init [radeon]] *ERROR* failed to create device file for power method

Does anyone have an idea ? I don't have any Xorg conf file

Re: Issue with radeon driver

Try updating the drivers.

yaourt -S xf86-video-ati-git
yaourt -S mesa-git
