Screen trembles on web browsers Leap 16.0

Hello,
I updated my Leap from 15.6 to 16.0 using updater from YaST. Now, my Firefox and Chrome display tremble. Especially in Google-chromme.

What it needs to be added to make things right?

This is my repository list:

Thank you for answering my questions.

I don’t know the actual solution to your problem, sorry.

But just recently, you posted

Then afterwards and just now:

Already back then it was said:

Maybe, your system is somehow badly scrambled?! In the past, your repo list was not OK at all, and it still isn’t for some aspect.

Maybe, during your upgrade, some things got mixed up and damaged.

What to do now — besides a fresh and clean install! — I don’t know, sorry.

I did not touched anything in last upgrading. Also, Snappy Repository is disabled. I 've had to do this upgrade because time is running out for Leap 15.6, and also I have problems to partitioning disc with agama installer. I know fresh installation is solution, but there are some crucial questions. Thank you for your effort to help me.

A solution may depend on your GPU(s). Please show inxi -GSaz here using PRE tagging (</> icon), or place your paste in between two lines containing only ``` on each, to preserve inxi’s formatting.

When inxi -G is run from a tty instead of within an X session, some of the data presented is either misleading and/or incomplete. e.g. you can see it says “unspecified” for Display, and “Console: pty” instead of the DE you are using.

Anyway, I have an Oland OEM as well, but in a PC not supporting 16.0, so cannot try to reproduce. You can try at your Grub menu appending the following to the linu line after striking the E key: radeon.si_support=0 amdgpu.si_support=1 before proceeding with boot. This should switch you from using the old radeon kernel module to the newer amdgpu for that one boot.

Also if you are using Wayland, try X11, and let us know if either makes any difference.

@vajcek Consider switching to the amdgpu driver?

I use an additional option as well as the ones provided by @mrmazda… rd.driver.blacklist=radeon

My full entry is amdgpu.cik_support=1 amdgpu.si_support=0 amdgpu.ppfeaturemask=0xffffffff rd.driver.blacklist=radeon

8

AFAIK, only the relevant xf86 package provides blacklisting radeon, if not running Xorg, then add the option blacklist option and get the best of both worlds…

Part of my setup script for AMD;

if [ $AMD_GPU == 1 ]; then
echo "Adding AMD GPU options"
update-bootloader --add-option amdgpu.cik_support=1
update-bootloader --add-option amdgpu.si_support=0
update-bootloader --add-option amdgpu.ppfeaturemask=0xffffffff
update-bootloader --add-option rd.driver.blacklist=radeon
update-bootloader

@malcolmlewis - I am not in this kind of programming, and never supposed that I wolud have to know anything of themes you asked me. :slight_smile: For example, your “nomodeset” I never heard before in my life. :slight_smile: If I just knew how to handle with partitioning, I would install this 16.0 long time ago. :slight_smile:

Where I have to make changes you suggested? If you could, ofcourse. :slight_smile:

10

@vajcek as suggested by @mrmazda add those options at boot to test, just to be sure add rd.driver.blacklist=radeon boot, if all good in the output of inxi -GSaz, you can make these permanent by switching to root user and run;

update-bootloader --add-option radeon.si_support=0
update-bootloader --add-option amdgpu.si_support=1
update-bootloader --add-option rd.driver.blacklist=radeon
update-bootloader --config

Above is approximately what you should see in an Xorg/X11 session using my previously suggested kernel command line options in Grub, just with 16.0 software versions instead of Tumbleweed and KDE3. :wink:

@mrmazda User is running Wayland, lets stick with that as this is the default going forward.

If I understood right, i have to type this:

radeon.si_support=0 amdgpu.si_support=1

Where to add

rd.driver.blacklist=radeon

What does in mean:

if all good in the output of inxi -GSaz

Where I can see if it is good?

I know how to enter GRUB menu, but where to add things I mentioned - I am not sure (or, better - don’t know).

Sorry for my rookie questions, but I really want to make this works perfectly as I accustomed during all there almost 20 years of using OpenSUSE.

Thank you for answering my questions.

14

All are for grub at boot, so add them all and if/when these work you can use that update-bootloader command to make it permanent.

15

I tried - everything is perfect: nothing trembles, nothing flickers (this trembling, flickering happened in Google chrome the most; I even can say only, but it was frustrated that you can not use one of web-browsers).

But: time after time, display freezes and got dark

Now, I have got some questions:

What is inxi -GSaz ? Is it something I have to type in console, or something other? And, at the end of my question-list:

update-bootloader --add-option radeon.si_support=0
update-bootloader --add-option amdgpu.si_support=1
update-bootloader --add-option rd.driver.blacklist=radeon
update-bootloader --config

section above type in terminal as root user (I suppose yes, but question more is better than mistake more) ?

Thank you for answering my questions.

16

It’s the same thing you did in post #5 here, typing it in Konsole.

When you reboot to start over after this happens, do the following in Konsole and copy and paste here the result:
sudo journalctl -b -1 -p3.

17

Hi, yes this makes the changes and saves for when you boot the system so no need to add manually.

18

My friends, what else can I say but thank you! You are just wizards! I did these update-boot lines (after I edited grub) , so now there is no trembling and flickering. I wait to see if display will get dark.

19

This is result
