Screen flickering and freezing after clean install 16.04

I just did a clean install of 16.04.

When I boot up the computer the screen flickers occasionally and eventually freezes. I also frequently get corrupted graphics.

My gpu is a Radeon R9 390. It is listed as supported by the radeon driver(which is the driver handling my gpu) for 14.04 and 15.10, but there is no support info for 16.04. It is also not listed as supported by the amdgpu driver.

I had 15.10 installed before the clean install of 16.04 and had no problems at all.

Any ideas?

Sometimes when the screen freezes it switches to a TTY and throws errors like this:

[   48.836874] [drm:ci_dpm_enable [radeon]] *ERROR* ci_start_dpm failed
[   48.836898] [drm:radeon_pm_resume [radeon]] *ERROR* radeon: dpm resume failed
[   49.008389] [drm:radeon_pm_resume [radeon]] *ERROR* radeon: dpm resume failed

Updating to Kernel 4.4.8 did not help.

Here is the output from lshw -C display.

I ran sudo update-pciids to get this to recognize it as the correct gpu.

I did another clean install. I tried doing a clean install of 15.10 and 14.04 but in both cases the install would freeze. So I ended up installing 16.04 again.

Now when it boots up it will freeze then after a lot of flickering and graphic corruption it will start working again. About every 3rd or 4th boot it will freeze and not come back requiring a reboot.

#2

It's now freezing everytime. The most recent time the screen went black and had the following lines visible:

/dev/sda5: recovering journal
/dev/sda5: Clearing orphaned inode 262816 (uid=1000, gid=1000, mode=0100600, size=0)
/dev/sda5: clean, 265908/1831424 files, 1658231/7324160 blocks

Solution 1:

This may be a power management problem.

Try this; At the grub menu, press E. If you grub menu doesn't appear automatically, press SHIFT when you first power on the computer.

On the line that says GRUB_CMDLINE_LINUX_DEFAULT, go to the end, and right after quiet splash, add radeon.runpm=0 and then press F10 to boot.

If the problem is gone, you can make the change permanent by doing the following :

• Open a terminal window, and type sudo nano /etc/default/grub to edit your grub file.
• Find the line similar to what you edited before, and again, add radeon.runpm=0 after quiet splash. Press CTRL+O, ENTER to save, and then CTRL+X to exit.
• Finally, run sudo update-grub to update grub. This option of disabling power management will now be permanent.

There are also other suggestions in a bug report suggesting radeon.dpm=0.
