Screen coming out of the monitor

Hi, Randomly a gap appears at the bottom of my screen, as if it had been moved a few pixels off the monitor. If I move the mouse cursor to the top of the screen, it appears in the small space that formed at the bottom. This problem does not usually appear every day, when this happens restarting the computer puts the screen back in place. The gap does not appear in screenshots.

That seems a hardware problem. Try to auto tune your monitor.

I don’t think it’s a hardware problem. I used other distros and did not observe this behavior, I have dual boot with Windows 10 and also had no problem with the screen on that system. And in addition it is a notebook, there are no adjustment options for the monitor other than brightness.

Yeah, your right, it can be an adjustment problem. Given your experience with other SOs, it also doesn’t appear to be a hardware problem.

Try to disable fast boot in Windows, then shut it down (don’t hibernate) and boot Manjaro. I’ve seen cases where Windows leaves some device settings behind which affect Linux. You can also test this by shutting the computer down, disconnecting it from the power source, removing it’s battery and plug it all again and boot Manjaro.

If the problem persists it may be better to write xorg config files and try some driver options.

I had problems with fast boot before, so it is already disabled. My system has already had updates in the graphics drivers and even in the kernel without any effect on the problematic behavior. I don’t know what the xorg config files you mentioned are, but I’ll look into it. Thanks.

So this started happening out of the blue?

I think this problem has been around since I installed the system, probably about 3 months ago. It is not a frequent thing, if it were I would have reported it before, I just have to restart the system that this problem should take a few days to manifest again. I tried to find a solution on the internet before but I didn’t find it, so the last time the gap appeared on my screen I decided to ask here.

Take off your 3D glasses. :stuck_out_tongue_winking_eye:

Good one.

Please post the output of mhwd -li

I think writing a xorg config file with tearfree option for the intel driver could potentially solve the problem. But since your computer has two graphic cards, I must know exactly what drivers you have installed.

Ok, let’s try to write a config file. There is always the possibility of the system failing to boot. In that case press CTRL+ALT+F2, login and manually delete the file. If, for some weird reason, you can’t change tty, press e on grub menu, navigate to the line starting with linux, then press END, SPACE, write 3 and press F10 to boot to a terminal and then delete the file manually.

Let’s call the file 91-intel-nvidia.conf (the 91 is important). Put this in the file, save and then reboot:

Section "Device"
  Identifier "iGPU"
  Driver "modesetting"
  BusID           "PCI:0:2:0"
  Option          "TearFree" "true"

  Identifier "iGPU"
  Device "iGPU"

Section "Device"
  Identifier "dGPU"

I created the file, there was no boot failure. I will wait a few days to see if the problem has been solved. Thank you

The xorg file did not solve the problem, it appeared again today.
