Hello ,
First excuses for the "test" I abusively did sent .
I have a new machine : Dell Inspiron 3721 , disk 1 TB, VGA
compatible controller 3rd generation Rev.09 Intelcorp and Radeon HD
8730 M , Mem size 8 Gb.
First as a general troubleshooting tool, have you applied all updates
and rebooted into the latest kernel? Some of the issues below might be
already fixed.
First problem :
I cannot adjust the brightnes of the screen.
There's been a lot of work on this in recent kernels. Do try the most
recent updated one.
Did you install in 'basic' graphics mode and/or are passing 'nomodeset'
on the boot line? If so, that could be the problem as that will cause
you to get the VESA graphics driver that can't do lots of things.
Second problem :
When booting I get the message
[2.234578] drm:cpt-error-serr-int-handler *ERROR* PHC encoder A FIFO
underrun.
Third problem :
After login I get the message : GDBus.Error.org.free
desktop.Policikit1.Error.Failed :
An autification agent already exists for the given subject.
Is that in a pop up? Dialog? When you do something?
Fourth problem :
When rebooting I get the message : [429.0649464] watchdog watchdog0:
watchdog did not stop !
Odd. Watchdog shouldn't be enabled by default. Did you configure it any?
Fifth problem :
When halting the system I get the following message and thereafter I
have to power off manually :
[439.308512] radeon 000:01::00.0:ring3 stalled for more than 1000msec
[440.686009] [drm:r600-ib-test]*ERROR*radeon:fence wait failed (-35)
[440.686050] [drm .radeon-ib-ring-tests]*ERROR*radeon failed testing
IB on GFX ring (-35)
[440.6860931 [drm:radeon resume-kms]*ERROR*ibring test failed (-35)
No idea off hand. :(
