Description diegogullo 2016-08-11 20:40:26 UTC 
after kernel upgrade i moved from fglrx to radeon on my HD 5770 as apparently old proprietary drivers are not supported anymore.

---kernel
$ uname -a
Linux bizmate-i7 4.4.0-34-generic #53-Ubuntu SMP Wed Jul 27 16:06:39 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

As two screens are currenlty mirrored (instead of extending) and using a non optimal resolution I wanted to configure xorg.conf to force a better set up. It used to work before upgrade

So i start by

$ xrandr -q

   720x400        0.00

I cannot see the screens here so i assume xrandr has a bug as i was expecting at least two entries.

I assume the current bad experience with the driver is a bug as my gfx is supported in theory by radeon out the box. Also xrandr looks very buggy on my system. 

Any thoughts? Should i add more info?
Comment 1 Alex Deucher 2016-08-11 20:59:11 UTC 
Please attach your xorg log and dmesg output.  It looks like are using a generic driver like vesa or fbdev rather than the native radeon driver.  Maybe radeon is still blacklisted from when you had fglrx installed.

no blacklisting in modprobe

$ grep radeon *

Comment 6 Alex Deucher 2016-08-11 21:18:15 UTC 
The radeon driver isn't loaded.  It looks like radeon is blacklisted from when you had fglrx installed.  Stop X and see if you can manually load radeon (modprobe radeon).
Comment 7 Alex Deucher 2016-08-11 21:20:09 UTC 
Also, please attach your dmesg output from a fresh boot.  It doesn't contain any driver messages, just docker spam.
Comment 8 diegogullo 2016-08-11 21:36:53 UTC 
sudo modprobe radeon

modprobe: ERROR coult not insert 'radeon': Invalid argument
Comment 9 Alex Deucher 2016-08-11 21:40:43 UTC 
Do you have nomodeset or radeon.modeset=0 set in your grub config?
Comment 10 Alex Deucher 2016-08-11 21:41:11 UTC 
Try modprobe radeon modeset=1

Dmesg.log

dmesg after reboot
Comment 12 Alex Deucher 2016-08-11 21:44:25 UTC 
There's the problem:
[    0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-4.4.0-34-generic root=UUID=315979a7-13a8-49cf-bd7a-616f29ad8c79 ro acpi=force nomodeset
remove "nomodeset" from your grub config.
Comment 13 diegogullo 2016-08-11 22:10:58 UTC 
that fixed it, 
also xrandr -q works now and sees the monitors
i wonder why i had this enabled as apparently it is just an option to stop the kernel from loading drivers and such. 
Anyway thanks a lot and i am pretty sure xorg cant do much for this to detect such problems
Comment 14 Alex Deucher 2016-08-12 13:41:30 UTC 
It may have been leftover from fglrx.
