Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.19 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

I'll ping upstream for feedback if v4.19-rc4 still exhibits the bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1791321 Title: No video on laptop display after suspend/resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1791321/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Yes, the test kernel you uploaded works fine. Thanks. I wish I understood more of what was behind that bad commit and the previous ones it referenced, since there appears to have been a series of fixes/reversions already, with each one apparently causing new problems on some other system: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c3a696b6e8f8 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=662591461c4b https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3cd091a77393 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1791321 Title: No video on laptop display after suspend/resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1791321/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1791321] Re: No video on laptop display after suspend/resume
I built a test kernel with a revert of commit 3cd091a773936c54344a519f7ee1379ccb620bee. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1791321 Can you test this kernel and see if it resolves this bug? Note about installing test kernels: • If the test kernel is prior to 4.15(Bionic) you need to install the linux-image and linux-image-extra .deb packages. • If the test kernel is 4.15(Bionic) or newer, you need to install the linux-modules, linux-modules-extra and linux-image-unsigned .deb packages.

3cd091a773936c54344a519f7ee1379ccb620bee is the first bad commit commit 3cd091a773936c54344a519f7ee1379ccb620bee Author: Rafael J. Wysocki Date: Fri Feb 9 22:55:28 2018 +0100 ACPI / EC: Restore polling during noirq suspend/resume phases Commit 662591461c4b (ACPI / EC: Drop EC noirq hooks to fix a regression) modified the ACPI EC driver so that it doesn't switch over to busy polling mode during noirq stages of system suspend and resume in an attempt to fix an issue resulting from that behavior. However, that modification introduced a system resume regression on Thinkpad X240, so make the EC driver switch over to the polling mode during noirq stages of system suspend and resume again, which effectively reverts the problematic commit.
