[Desktop-packages] [Bug 1553441] Re: Only one monitor working at the time (xserver-xorg-video-ati)

lazanet, to clarify, I never said don't send logs.

Despite this, the issue you are reporting is an upstream one. Could you
please report this problem via
https://bugs.freedesktop.org/enter_bug.cgi?product=xorg=Driver/Radeon
?

Please provide a direct URL to your bug report once you have made it so
that it may be tracked.

Thank you for your help.

[Desktop-packages] [Bug 1553441] Re: Only one monitor working at the time (xserver-xorg-video-ati)

2017-01-14 Thread lazanet
I realized that I haven't tested HDMI output on radeon driver (and 17.04 with 
mainline kernel), so I decided to test it out.
Initially, after plugging both VGA monitor (ASUS), and HDMI TV (VOX), HDMI and 
VGA outputs were showing image (however at 1080i, image was buggy and scrambled 
at TV screen) while internal monitor was off. After changing TV resolution to 
1280x720 image was looking ok. 

After changing resolution options, I was able to output image on both
VGA and HDMI or internal monitor and HDMI (but never all three or VGA
and internal monitor at the same time). So, except that 1080i glitch
(which can be seen on provided image), HDMI would always be on and
functioning.

Interestingly enough, even with same resolution options, VGA and
Internal Monitor would work seemingly at random (at first setting of
that resolution combination internal monitor would work and VGA
wouldn't, but if I set same settings again later VGA would display image
and internal wouldn't).

I know that you told me not to send logs, but I believe that they might
be relevant (especially for HDMI@1080 bug).

Title:
  Only one monitor working at the time (xserver-xorg-video-ati)

Status in xserver-xorg-video-ati package in Ubuntu:
  Incomplete

Bug description:
  When external monitor is connected to VGA port (AMD Radeon 7470m)
  internal laptop monitor stops working. I'm able to set laptop monitor
  as primary which disables external monitor (and vice-versa). Tried
  manual switch to mainline Linux 4.5 kernel, same thing. Tested on
  14.04, 15.10, 16.04 with same results.

  WORKAROUND: Use Ubuntu 14.04 with fglrx.
