[RESPONDED] Framework forgets external monitor resolution on wake from sleep

Framework Laptop 13 Linux
1

I have an 11th gen framework (original DIY edition) running Ubuntu 22.04. For use at my desktop, I typically connect it to an external LG 34WK95U 34 inch 5120x2160 monitor, along with keyboard and mouse.

About once every 3-4 times when I wake the machine from sleep, it seems to forget that the 5120x2160 resolution is available and display a distorted 2560x2160 screen. In settings I can choose other resolutions up to 4K, but not the correct 5120x2160. This happens whether the monitor is directly connected to the USB-C port on the laptop or using a Thunderbolt 3 dock. Restarting the laptop consistently fixes the problem, but it’s a pain to have to restart on wakeup so often.

Does anyone know what might be causing this and how I can fix it? In general waking from sleep with the lid closed has been a bugaboo of this laptop since I bought it-- half the time the external KB/mouse doesn’t even work to wake it up and I have to open the lid, the other half of the time it does work but is really slow-- and a recurring stumbling block for smooth home use. I don’t know how to tell if it’s the laptop HW or the Linux SW at fault.

Does the same thing happen on other devices? Does this happen regardless of which distribution you run? Do other monitors/cables work?

I currently have issues with a specific KVM-Switch. As soon as I replace it and connect it directly to my Framework, it instantly and always connects to it, no matter if after suspend or restart.

What is your current state of PS2 emulation? Have you tried booting with the kernel parameter i8042.nomux=1 (and possibly even i8042.reset) to see if that makes a difference?

3

This is almost always a software meets dock issue. What connector are you using on the monitor to dock or monitor to laptop?

I have a dock that does not like Gnome Screenlock. So I disabled it, and set it up to suspend instead. Now it detects my monitors flawlessly.

4

To the last couple of questions:
– This does not happen when I connect a MacBook Air to the same dock and monitor.
– I haven’t tried a different Linux distro, but am happy to if anyone can recommend a distro that seems to support external devices and/or sleep/wake cycles better.
– Haven’t tried other monitors/cables because I don’t have any at hand. Both the monitor cable and dock cable are Thunderbolt certified cables with the thunderbolt logo on them, and again I’ve tried both a direct monitor → laptop connection and a monitor → dock → laptop connection (with two different docks actually, a CalDigit TS3 Plus and an OWC Thunderbolt Dock, same behavior).
– Good suggestion on the PS2 emulation parameter, I’ll try that, thanks.

This is sounding very similar to the screen lock issue I was having with Fedora 37. I suspect it has to do with how Gnome handles the lock and then after a prolonged period the transition to suspend. Try directly suspending from a terminal and see if when you wake it back up if it continues to occur. This is almost definitely a Gnome issue, and possibly a Wayland only issue. I did not dig into whether it was occuring on Xorg. Since I disabled screen lock and began using suspend instead (tied it to the screenlocking keyboard shortcut) I have had not issues with screen resolution on resume, or with discovery of the monitor.

6

Thanks, that’s helpful. It does not appear to happen when suspending from the top right menu or using systemctl suspend. I switched to Xorg awhile ago due to earlier problems with Wayland, so it’s not a Wayland issue, but it may well be a Gnome issue. I’m willing to just use a different desktop environment than Gnome, but less radical workarounds would be nice too. Can you say more about the steps you took to disable screenlock and use suspend tied to the screenlock shortcut instead?

7

Under settings go to power and turn screen blank to never. Then go to keyboard in settings and view and customize shortcuts. Under custom shortcuts create an entry named Suspend, the command should be systemctl suspend and the shortcut Super+L. It will warn that it is already being used, ignore the warning and proceed. This will disassociate screen lock from Super+L and now it will suspend instead with that shortcut.

Hope that is less radical than switching desktop environments :slight_smile: I stopped looking as switching DE’s as an option several years ago, you always trade one problem for new ones.

I echo everything @nadb has said thus far. Linux and docks are “fine”, until they’re not. Suspending with a dock on Linux isn’t something I personally recommend.

9

@Matt_Hartley Is the issue docks per se, or Thunderbolt? Because the resolution issue happens even when the monitor is connected directly to the Framework Laptop’s USB-C port via its own direct Thunderbolt cable. I’m wondering whether it’s worthwhile to try connecting the monitor with a DisplayPort or HDMI cable instead.

10

@Nicholas_Weininger it can be any of those. How is the dock handling the display? Is it using displaylink without you knowing it? Is it using MST? Does the chipset have a quirk that the chipset on your laptop does not like? Is the firmware on one or the other glitching just enough to cause an issue? Is the dock usinng a Realtek Ethernet chipset…yeah had that one bite me before. It is entirely possible that switching your cables to displayport or hdmi or usbc and switching which monitor goes to which port on the dock could easily change the equation in your favor. Thunderbolt is a pain, things that should work on paper, simply don’t. I have had docks that were supposed to be compatible with a very specific laptop not work well with it, but perfectly with one off the list. Also the software stack does matter. Is there a kernel regression, is i915 messing up the handoff from plymouth to gdm, is bolt breaking something that only breaks on a small handful of docks, is MST dealing with a persistent bug…anyone who thinks thunderbolt should simply just work because all the parts have the Thunderbolt Certification is likely somewhat delusional.

In short yes try it. If you have the cables why not. It might just work.

Anyway sorry for going on but I just had to return a Plugable TBT4-UDZ because it refused to be detected on boot. After a ton of troubleshooting I got it to see the dock until I decrypted my drive and then the screens would go blank, I would get to the login screen. Sign in, check boltctl and sure enough the dock is listed as disconnected. Power cycle and it comes right back up. Caused slow boot on a reboot, and then got lost. Hotplugged fine. Kept moving the location and scaling of every screen between boots. Basically unusable…but it worked under some conditions.

So still shopping for a new dock, and out of curiousity I wanted to ask you how the OWC Thunderbolt Dock is since it was on my shortlist. My Lenovo Thunderbolt 3 Dock (First Gen) works great outside of the similar issue to the one you are experiencing but I want something with more power delivery hence why I am playing the return game.

Anyway good luck.

The OWC dock works just fine other than this monitor issue. I had previously tried a CalDigit TS3 Plus, which had different monitor failure issues (like the monitor often not waking up at all until I unplugged it and plugged it back in) and also had a couple of the USB ports just inexplicably stop working sometimes.

This is a good question. The moment we insert non-Framework hardware into the equation, we are left sifting through logs and trying to replicate without said dock here locally.

Now, you did indicate the behavior is happening with a direct connection. This is helpful as this tells us that the distro is failing to do its job in remembering this.

DP and HDMI connected through the Framework expansion cards and using off the shelf cables should remember your resolution successfully.

Just tested 1920x1200 16:9 over HDMI using our HDMI expansion card (odd monitor to laptop comparable, wanted something to test that was similar available resolution.

Went into deep suspend. Woke up the Framework on Ubuntu 22.04, resolution resumed correctly for both screens.

13

OK, thanks. I ordered a DP expansion card since the monitor has a DP 1.4 port, and I’ll report back whether that fixes the issue (though again, it’s hard to tell from a single test since it doesn’t happen every time or even most of the time, just often enough to be annoying :))

14

I tried running a DP cable to the monitor’s DP port directly from the Framework expansion card. That works resolution-wise, but the display goes blank for a second every 5 or so seconds, making it unusable.

FWIW, on my other note, the PS2 emulation change nadb suggested does seem to make wake from sleep work, but I still observe that the laptop takes multiple tries as well as a very long time to wake from sleep in response to USB input. It seems to be trying to wake up, failing, going back to sleep, then waking up properly on the second try. I’ve tried this with a keyboard connected directly to the USB-A port on the laptop, so it’s not a dock issue. I’ve also checked that the relevant device has its /power/wakeup file set to enabled.

15

You should see this on the kernel log then (dmesg). Can you take a loot and copy what is printed there?

16

Sure. I just reproduced the issue and piped dmesg output to a file, of which the most recent bits are pasted below. Apologies for the verbosity, the upload function on this commenting interface only seems to want to let me upload images. Let me know if you want any earlier subsets of the file or if there’s another way to upload the whole thing.

You may have resolved this or found a workaround but it appears to be an issue with multiple versions of Linux and compatibility with certain screens and/or docks.

[ 1803.350848] i915 0000:00:02.0: [drm] ERROR CPU pipe B FIFO underrun: transcoder,
[ 1999.473594] i915 0000:00:02.0: [drm] ERROR CPU pipe C FIFO underrun: transcoder,
[20933.270877] i915 0000:00:02.0: [drm] ERROR failed to enable link training

Those CPU pipe B/C FIFO errors are what’s causing it. There is a suggested solution in the link below but from searching for those errors it seems multiple solutions have been tried and some solutions aren’t permanent or effective for different versions of Linux or hardware.

Marking this thread as responded.

We recommend using expansion cards with direct connections over docks for connecting displays.

FWIW, when I changed my setup to not use a Thunderbolt dock at all but only a “regular” USB-C dock, the issue disappeared. I have two USB-C expansion cards on the laptop, I connect one to the new dock for all the rest of my USB devices and the other to the monitor, and the monitor resolution has been consistently stable since that change.

I still do consistently have the other issue I described earlier, where the laptop takes two tries to wake up from sleep-- this is more of an annoying delay than a functional issue, though.

This aligns with my findings. Glad to hear this is resolved.

It’s worth checking journalctl -b
to see if anything shows up when this happens.
