[Bug 1878421] Re: Using two GPUs with one monitor each, one is always black
after my laptop-screen goes off (automatic locking of workstation) and i retouched it to go on again, i see some flickering on the external monitor with background-image, but it looks like there was heavy load so that login-screen wasn't displayed (see also background on internal screen)...have now switched off external monitor to get login-window again...maybe this helps to get the issue nailed down -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1878421 Title: Using two GPUs with one monitor each, one is always black To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1878421/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
