Hi,
I did all of the above and it seems better but it isn't completely gone. I don't notice the strange split when I am scrolling video pages like youtube anymore but I am still noticing a little break watching a video.
I am using brave and have a VPN running, if that makes any difference.
You also could try:
i915.modeset=1
or
i915.enable_dc=0
and see if you get better results. If you run into trouble, tap the esc key starting at the motherboard splash screen to pull up the Grub Menu. Select Advanced Options for Zorin > Recovery
Arrow key to the last option to Drop To Prompt and use
sudo nano /etc/default/grub
to revert the changes if needed to restore access and functionality. Be sure to remember after each change to run
sudo update-grub
for the changes to take effect.
Ok, so I tried all three options but none of them have solved the problem completely. I feel that the first option did the best job but it wasn't 100%.
Q: what is the motherboard splash screen?
Any other ideas of what I can do?
Hi,
I just pressed the ESC key when booting my laptop and all I see is grub. Grub grub no commands that I can press?
I tried putting in the advanced command but it just returned can't find command
Can we test:
sudo nano /etc/default/grub
Change:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
Tap ctrl+x to exit the document editor, then the y key to say Yes to save, then the enter key to save the current configuration.
The terminal will revert to normal.
Now run
sudo update-grub
Reboot and test...
If that helps the issue, it at least gives us some idea of what is going on.
You will see higher power consumption and less acceleration in this mode.
For now, we are testing one aspect of the Graphics driver, so we can ignore that loss of screen rotation temporarily.
Can you test videos?
Yes. I have to come back to this in an hour or so. But so far it looked normal.
Ok I tested a bit more and the video seems to work just fine. On second thought it is still causing the line when it is a fast moving image.
Also when I change from full screen to small the browser was blacked out in corners. Once I go over it with the mouse it is back.
Ok... So it appears this may be a known upstream bug.
I wonder if the linux-oem-kernel may function better.
What result do you get from:
sudo apt install linux-oem-20.04
Ok, i did that and no real change. The line is still there.
What result did you see in terminal when you ran the installation?
It downloaded the whole program and then i rebooted it...
Did you use Advanced Options for Zorin from the Grub Menu to select the kernel to boot from?
I just typed in reboot into terminal
You can access the Grub menu at boot by tapping the esc or the tab (some computers) key.
Wow sorry, the grub menu is the thing that shows up when I press F2 and end up in the boot settings window?
Ok I googled it. think I tried that in the past with no success. But I try again, now.
Esc. didn't work.
Tab neither.
Are you booting Legacy or EFI?
You would have seen whether you are booting and installing as Legacy or as EFI at the time of install.
For a 2020 machine with your other setup, it seems highly likely that you are on EFI...
Maybe tap the esc key a bit more viciously?
It can take a couple tries...
You can also check
cat /etc/default/grub
and ensure that your timeout is not set to 0.
I recommend 10
GRUB_TIMEOUT=10
