Operating system data:
Linux 5.15.0-46-generic #49-Ubuntu SMP Thu Aug 4 18:03:25 UTC 2022 x86_64 x86_64 x86_64 x86_64 GNU/Linux
Description: Ubuntu 22.04.1 LTS
Release: 22.04
Just installed. When testing Ubuntu there was no problem.
Device data:
Dell Precision 5530 2in1 (Kaby Lake-G workstation)
| Intel Core i7-8706G
| Radeon WX Vega M GL, 4K UHD
What happens:
With kernel to 5.15: Before logging in, just after selecting the linux kernel from grub, the screen goes black, no ubuntu+dell loading screen, no nothing. With the black screen, random vertical and horizontal lines appear and move if the cursor moves. There is no way around this, and the only alternatives to change this is:
1. close the laptop lid (sleep mode) and restart.
2. Connect an HDMI to the USB-C port and then disconnect it.
If either of the two steps is followed, the display corrects itself and works perfectly.
This happened to me using
- Ubuntu 20.04 with Linux 5.15.0.43-generic
And now that I upgraded it also happens to me
- Ubuntu 22.04.1 with Linux 5.15.0-46-generic
The error did not appear in using
- Ubuntu 20.04 with Linux 5.13.0-52-generic or earlier
I will provide all the information you see necessary to solve the problem. |
