[Bug 1924624] Re: After upgrade to kernel 5.8.0-49/50 with Intel Gen7 (Haswell/Ivy Bridge/Bay Trail) graphics a lot of glitches render screen unusable
I was using linux-image-5.8.0-55-generic:amd64 - this kernel still has the issues. Reverting to 5.8.0-48 removes the issues. Changing to the 5.4 kernel (latest) also removes the issues -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1924624 Title: After upgrade to kernel 5.8.0-49/50 with Intel Gen7 (Haswell/Ivy Bridge/Bay Trail) graphics a lot of glitches render screen unusable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1924624/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1766217] Re: software updater presents an empty panel for updating
Have this same issue in 20.04 with xubuntu. If launching via menu launcher - it runs with no parameters (update-manager) - and it reports that there are 400+MB of updates required, but I get no details of what they are. If launching from shell with no-update parameter (update-manager --no-update) all is shown OK. Using command line tools, there are presently NO security updates available, just non-security updates. /var/lib/apt/extended_states_tmp has thousands of lines present (so I dont know which line is affecting behaviour here) - but if this file is moved aside - all works as expected. Dont exactly know what purpose this file has (know what its for - but not what consequences of removing it are) so want to leave it in place. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1766217 Title: software updater presents an empty panel for updating To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1766217/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
