Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to review all reported bugs in a timely manner.
Ubuntu 16.04 (xenial) reached end-of-standard-support on April 29, 2021. I'm setting the status of this bug to 'Incomplete' as it's not seen any activity for some time. If this is still an issue when using a currently maintained release of Ubuntu then please let us know which one(s) otherwise this bug report can be left to expire in approximately 60 days time. ** Changed in: xorg-server (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1771331 Title: [radeon] boot error, low resolution graphic mode Status in xorg-server package in Ubuntu: Incomplete Bug description: This error only takes a short time, I suppose it must be due to some update of the Kernel or due to a change in Xorg. It does not always happen, only on some occasions when (re) starting the system the error "graphic mode in low resolution" appears but the appearance of the desktop is the same. I do not use high resolution graphics or 3D games. Only typical desktop applications.
