Built-in laptop screen is laggy even when external monitor is not a problem

I have installed Ubuntu 22.04 on a ROG Flow Z13 (2022). I have a samsung screen (LS34A650UXLXZX ) connected with USB-C. Both have been working ok, but recently I noticed that in the built-in screen the mouse, the keyboard even dragging a window to that display is very laggy. Meanwhile in the external screen there is not such a problem. I have installed nvidia-driver-470-server

I tried to upgrade to nvidia-driver-525, nvidia-driver-515, including the server versions but after reboot the second screen is not recognized and the built-in screen remains laggy. Even is to hard to go back because the slowly mouse and response.

Also, I tried to use noveau but the problem persist.

If I unplugged the external monitor, the built-in screen still laggy. I have tried to change resolution also the refresh rate and the problem doesn't fix it.

I also disabled the secure boot option but nothing.

Update Mar 15

I tried this and nothing fix it: a) Switch xorg to wayland. b) Different desktop (XFCE) c) Use lightdm, c)Switch between nvidia-performance and nvidia-ondemand in nvidia-settings, d)run ubuntu with previous kernel, e)different frequency 120Hz to 60Hz, f)different scaling, g)Check if Meltdown patch has been applied. The courious thing is even using without external monitor the problem persist. I thought was hardware issue and I used Windows an worked normally. Any ideas?

Update Mar 15

Sorry, also I have searched a lot and it seems nobody reports such a thing.

Update Mar 20

I ran ubuntu from liveusb with different versions. With Ubuntu 22.04 and 20.10 laggy mouse and laggy windows resizing. With Ubuntu 20.04 works perfectly. With Ubuntu 18.04 doesn't even show the GUI, black screen. Any idea?

Update Apr 15

I installed kernel 5.17 and the performance was a little better but still laggy. The external monitor didn't work at all but It seems a driver version loaded probably; I didn't tried fix it.

Also I tried to change PowerMize to Prefer Maximum performance but didn't work.

Update Jun 4

I follow this: https://www.reddit.com/r/FlowZ13/comments/121arkr/how_to_fix_linux_on_the_2022_rog_flow_z13/ and this: Trying to set enable_psr=0 in /etc/default/grub, keeps being changed to i915.enable_psr=1

In /etc/defualt/grub add: "i915.tuxedo_disable_psr2=1 i915.enable_psr=0" in this line: "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"" This must be: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.tuxedo_disable_psr2=1 i915.enable_psr=0"

Then update-grub

reboot

I have been following this issue on Reddit and think that you may have a similar problem. See https://www.reddit.com/r/FlowZ13/comments/121arkr/how_to_fix_linux_on_the_2022_rog_flow_z13/

It suggests that the problem may come from the Panel self refresh feature in the Intel/Nvidia combination. This feature is designed to save battery energy when nothing is happening on the screen by slowing down the screen refresh rate.

Unfortunately, the Z13 triggering a bug that makes it always slow down for the monitors driven by the Nvidia.

Fortunately, there 2 boot time variables that can be set to disable the 'feature' and this: Trying to set enable_psr=0 in /etc/default/grub, keeps being changed to i915.enable_psr=1

In /etc/default/grub toward the top of the file there is a line that looks like

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

you are going to want to add i915.tuxedo_disable_psr2=1 i915.enable_psr=0 to the end of this line so that it is something like

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.tuxedo_disable_psr2=i 915.enable_psr=0"

run: % sudo update-grub watching the output to make sure that there are no errors. It there are, fix the errors, so that the finial time you run sudo grub-update it runs clean.

When you are ready -- % sudo reboot

Welcome to SE @vml! The link on reddit really helps, especially the update that explains that that the "panel update" feature (slow screen refresh when inactive) has a bug. I put some suggested edits into your answer that may add clarity. You can revert them after the get reviewed if you wish. Good research!

I had a similar issue. It was caused by a kernel update that happened in the background. If I dropped back to an older kernel (5.15), then the built in display would work and the external display would not.

The latest kernel seems to have fixed it. Try upgrading your ubuntu system. I'm currently on 5.19.0-38-generic and my built-in display is working again.

Thank you Motred. But it didn't work for me. I updated to 5.19.0-38 and nothing.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
