[Ubuntu-x-swat] [Bug 1886729] Re: Dell displayport YJ3Y6 adapter doesn't drive 4K screen properly
Thanks for pointing that out. I was wondering why so many adapters/cables for sale only mention "USB" while also claiming to do 4K60Hz... https://www.displayport.org/displayport-over-usb-c/ So Thunderbolt isn't required, only USB 3.1 Alternate Mode and a powerful (probably only *integrated*) GPU that can link to it. You might have hit some kind of bandwidth limitation using both USB-C ports at once. Although that doesn't make sense at Thunderbolt 3 speeds, it would make sense at USB speeds. And even if USB 3.1 speeds are being surpassed to support Alternate Mode your chipset/GPU might only know how to do it on one port at a time. So this might not be fixable... Also remember to try 'Ubuntu on Wayland' which uses a completely different code path for all this. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1886729 Title: Dell displayport YJ3Y6 adapter doesn't drive 4K screen properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1886729/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [Bug 1886729] Re: Dell displayport YJ3Y6 adapter doesn't drive 4K screen properly
Thank you for the response. I think these might fall into the third category of 'VESA is its own special story' ? I bought both the adapters from the dell configurator at the time I bought the machine. This is the part that flakes: https://www.dell.com/en-us/shop/accessories/apd/470-acfc The other part, that works fine It is advertised as suitable for 4K 60hz, which as you note exceeds USB3.1, but see the link from the dell site - https://www.usb.org/sites/default/files/D2T1-4%20-%20VESA%20DP%20Alt%20Mode%20over%20USB%20Type-C.pdf - it is not being carried over USB, but over alt-mode DP as far as I can tell, which should have plenty of bandwidth. The monitors are, from memory DP 1.2, requiring MST to operate - https://downloads.dell.com/manuals/all- products/esuprt_display_projector/esuprt_display/dell-up2414q_user%27s %20guide_en-us.pdf confirms this. However, the mystery deepens. There are two USB-C/thunderbolt connectors on the laptop. My initial report had the combined-power-HDMI-DP one in the left connector, and the DP only one in the right connector. On a lets-be-pedantic hunch I just plugged them in on the opposite sides. With the DP only adapter plugged in on the left side, it: - reports both the MST panels - both panels autoconfigure for a combined 4k 60hz - yay! """ DP-1-8 connected 1920x2160+5760+0 (normal left inverted right x axis y axis) 527mm x 296mm 1920x2160 59.99*+ DP-1-9 connected 1920x2160+3840+0 (normal left inverted right x axis y axis) 527mm x 296mm 1920x2160 59.99*+ 1920x1200 59.88 """ With both adapters plugged in, the DP only one still on the left side, the behaviour that I originally filed the bug because of returns: """ xrandr --output DP-3 --auto --output DP-1-8 --auto --output DP-1-9 --auto xrandr: cannot find crtc for output DP-1-9 """ If I turn DP-3 off I can run the single DP monitor fine even though the adapter is plugged in. This behaviour is also consistent if I switch the power/hdmi/dp adapter to use HDMI rather than DP. What I had hoped to do is to use - ideally - all three outputs, or at worst, two external outputs and have my laptop folded flat and out of the way while I use my clicky-clacky keyboard and real mouse at my desk; being able to use either adapter, one at a time, is a dissapointment. What I think this shows so far: - each adapter works independently, with either adapter, from either USB-C port. - something I don't know enough about yet causes some resource constraint or conflict when both external screens are in use. ** Changed in: xorg-server (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1886729 Title: Dell displayport YJ3Y6 adapter doesn't drive 4K screen properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1886729/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1886729] Re: Dell displayport YJ3Y6 adapter doesn't drive 4K screen properly
Hmm, it seems Thunderbolt-DisplayPort cables are pretty rare. Instead of searching for those I suggest looking for adapters that are explicitly for "Thunderbolt" and not "USB". USB 3.0 has a bandwidth of 5 Gbps USB 3.1 has a bandwidth of 10 Gbps 4K at 60Hz however requires 3840x2160x4 (33177600) bytes per frame, 265420800 bits per frame, or ~16 Gbps. USB never had a chance and at best would give you only 30Hz. So make sure your adapters are "Thunderbolt" and not "USB". Thunderbolt 3 in your laptop supports 40 Gbps which is enough for 4K at 120Hz. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1886729 Title: Dell displayport YJ3Y6 adapter doesn't drive 4K screen properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1886729/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [Bug 1886729] Re: Dell displayport YJ3Y6 adapter doesn't drive 4K screen properly
You certainly seem to have the latest and greatest Intel GPU which should support 4K up to 120Hz: https://ark.intel.com/content/www/us/en/ark/products/196597/intel- core-i7-1065g7-processor-8m-cache-up-to-3-90-ghz.html So I suspect using "adapters" is the main issue. If you can then please try to get a Thunderbolt-to-DisplayPort CABLE. The Thunderbolt end looks like USB-C but it's much more capable and can carry a full-speed DisplayPort signal. This is probably not a software bug, or if it is then probably not one we need to worry about if you just get a different cable. In the meantime you might want to try selecting 'Ubuntu on Wayland' from the login screen to see if the experience is any different there. ** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu) ** Changed in: xorg-server (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1886729 Title: Dell displayport YJ3Y6 adapter doesn't drive 4K screen properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1886729/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps: 1. Look in /var/crash for crash files and if found run: ubuntu-bug YOURFILE.crash Then tell us the ID of the newly-created bug. 2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us. 3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1. Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself. ** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu) ** Changed in: xorg-server (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1886697 Title: Xorg crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1886697/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [Bug 1886729] [NEW] Dell displayport YJ3Y6 adapter doesn't drive 4K screen properly
Public bug reported: I have some early dell 4k 60hz screens - the ones which report 2 panels internally for DP 60Hz - horrid hack I know; I recently got a new XPS laptop and put Ubuntu on it. That XPS laptop has two USB-C/thunderbolt ports, so to drive the screens I bought two slightly different DP adapters - one with power passthrough, and a cheaper one that only does DP. The more expensive one 'USB-C to HDMI/DP' drives the monitor happily over DP, though sadly only at 30Hz - can't have everything :/. It reports one monitor as one output: DP-1 in the attached information: DP-1 connected 3840x2160+0+0 (normal left inverted right x axis y axis) 527mm x 296mm 3840x2160 29.98*+ 30.0029.97 1920x1200 59.88 ... The cheaper one reports the single monitor as two distinct outputs, at 60hz interestingly - DP-3-8 connected (normal left inverted right x axis y axis) 1920x2160 59.99 + DP-3-9 connected 1920x2160+7680+0 (normal left inverted right x axis y axis) 527mm x 296mm 1920x2160 59.99*+ 1920x1200 59.88 which in theory if summed together would be one whole screen. But attempting to configure the output results in an error: xrandr --output DP-1 --auto --left-of eDP-1 --output DP-3-9 --auto --right-of DP-3-8 --output DP-3-8 --auto --right-of eDP-1 xrandr: cannot find crtc for output DP-3-8 I'm not sure if this is an intrinsic limitation of the USB-C->DP dongle, or whether there is something that can be done in the software to deal with this 10 year old hardware hack I have sitting on my desktop.

Alt-F2 and other routes have not been successful in recovery the Desktop GUI or log-in. However, if I stay at my computer and prevent the computer from sleeping, the job completes without GUI death. I don't know how to search the syslog, but I expect to find something funky around something like "GUI going to sleep". The reason I think it is a true "crash" is, despite being away from my the PC for 1 hr, the job directory is empty. This makes me think the computer processes were halted during the events that lead to the GUI death. I have played with my GPU settings.

I have XPS13 with second monitor, all working fine till I lock screen or suspend. Then my second monitor will not 'resume'. I.e. stays off. This behaviour started after (or shortly after) playing a wine game using Lutris to launch. Shutting game down and almost immediately hitting suspend on the laptop. Was rushing out. It's a wild shot in the dark but I think something got messed up / not saved correctly in this process. To get it working I need to unplug monitor (using USB-C > HDMI) > suspend > plug in monitor > resume and sometimes still need to open display settings before it 'kicks in'. Damn annoying.
