After kernel update display at 90 degrees went black

Postby aveintie » 2017/09/19 08:53:05

Hello, I wonder if anyone has ideas how to fix a situation with a rotated screen no longer working after this most recent update. It is a remote machine that worked just fine with a 1920x1080 display rotated 90 degrees. After update and reboot there's the login prompt just fine but when a user tries to log in the screen goes black. I see the below message repeating in /var/log/messages:

Code: Select all

Sep 19 11:20:49 localhost kernel: radeon 0000:01:00.0: evergreen_surface_check_2d:289 cb height 1080 invalid must be aligned with 16
Sep 19 11:20:49 localhost kernel: radeon 0000:01:00.0: evergreen_cs_track_validate_cb:431 cb[0] invalid (0x000000ef 0x00007e8f 0x00190880 0x01088468)
Sep 19 11:20:49 localhost kernel: radeon 0000:01:00.0: evergreen_packet3_check:1949 invalid cmd stream 486
Sep 19 11:20:49 localhost kernel: [drm:radeon_cs_ioctl [radeon]] *ERROR* Invalid command stream !


I created a new user remotely and the local user logged in using that account without issues. As soon as he tried to orient the desktop for the physical display I started seeing the same message and desktop became unresponsive till it reverted back to the horizontal setting.

I reinstalled xorg-x11-drv-ati.x86_64 just in case but that did not help.

/var/log/Xorg.0.log does not show errors or warnings.

What else should I inspect?

Apparently the issue is similar to another posted here before which I only just now noticed (in my case though, display is not only "garbled" but goes totally black). The other thread: 7.4: Garbled display with ATI Radeon HD 5450

Also tried this with another Centos 7 machine with Radeon 3000 which seemed to not have the issue. So I guess it is narrowing down to (at least) ATI Radeon HD 5450 having different issues with a rotated display.
