Linux Mint 21.1 Cinnamon - Second monitor freezes at seemingly random times | Linux For All | Page 1

(Sorry if some stuff is missing this is our first time doing something like this)
OS: Linux Mint 21.1 Cinnamon 5.6.8
Hardware:
HP Pavilion Gaming Laptop 15-ec0xxx
29.26 GiB Ram
AMD Ryzen 5 3550H with Radeon Vega
NVIDIA GP107M [GeForce GTX 1050 3 GB Max-Q]
AMD Picasso/Raven 2 [Radeon Vega Series / Radeon Mobile Series]
Monitor 2: XP Pen Artist 12
Error/Logs N/A
Problem:
At seemingly random times, the secondary monitor will freeze with whatever was displayed on it last. Turning off the display and/or unplugging it do not fix the issue.

The only way to (temporarily) fix this that we've found is to use the "Display" app to change the location of the second monitor. This will only work if the changes are confirmed (Keep New Configuration) and the problem will resume if the dialog box times out or the "Cancel Changes" button is pressed.

If anyone could give a more permanent fix to this, that would be great. Thank you for even checking this out!

First thing I would do is check the logs, ngl. My guess is that this could be a driver issue, but without double checking the logs, there's no way to fully ascertain what is happening.

If you have another monitor, that isn't the same brand/model, try using that and see if it also freezes there. If not this could also be an indication of that display tablet.

We'll check the logs, but as for a display tablet issue I'm pretty sure it's not that. This didn't happen when we were on Windows.

What log files should we look for?

When you face the “monitor keeps connecting and disconnecting” issue, you can check if there is loose contact or damaged cable. You can use the cable to connect to another monitor and test the cable. If there is still something wrong and the cable is faulty, you need to replace the cable with a new one.

We unfortunately don't have another monitor on hand

Alright here's the logs

#

#

No idea what they mean x.x

windows is a poor metric.

As for the logs, it is truncated and incomplete. It does not indicate anything useful.

Those are the logs from a little before the start of the incident to the time we took the screenshot. Is there a way we could get something that might be more useful?

At this point, I would simply open up terminal emulator, run journalctl -b and read from beginning till now. This is useful if the display tablet stopped functioning, otherwise it would be journalctl which would be from beginning of installation. There's also journalctl -b-1 for instance to show up previous boot entries.

Terminal emulator?

#

Is that just Terminal or is there something special we have to do

#

A terminal emulator, or terminal application, is a computer program that emulates a video terminal within some other display architecture. Though typically synonymous with a shell or text terminal, the term terminal covers all remote terminals, including graphical interfaces. A terminal emulator inside a graphical user interface is often called a terminal window.

I suppose just "terminal" can also work… normally I would associate that word alone with things like vt100 which is just one of various terminal out there.

And here's the logs from a recent event

That log alone isn't enough, there's no indication about the driver status in question or anything of the sort. It's also incomplete.

You need to provide exactly how you installed the driver for that display tablet, and a complete journalctl. As far as I know, digimend supports any other non-Wacom tablets, and support can vary greatly. If your vendor has their own drivers, it might be faster to see the options they offer with it, like support for Linux. Many don't support Linux, nor have proper drivers for Linux.

OH

#

Ok

#

I entirely misunderstood

gusty goblet Apr 22, 2023, 1:15 AM

#

I don't remember installing drivers to make the display work. But that's not, right, is it?

lime pelican Apr 22, 2023, 1:17 AM

#

Display tablets doesn't require drivers for the display portion, that is handled by your graphics card. It does, however, require a driver for interfacing with it, i.e. moving the cursor around with it.

gusty goblet Apr 22, 2023, 1:30 AM

#

And that could still cause issues with the display we presume?

lime pelican Apr 22, 2023, 1:35 AM

#

Possibly. I don't like to speculate, but given the little amount of information presented thus far, it is only possible.

After all, I could also point out that your gpu is of a lousy choice, and that may have also exacerbated your issue.

Unfortunately we're using a laptop, it wasn't really our choice :c

Unless we're thinking of something else
