[Touch-packages] [Bug 1625350] Re: High CPU usage of /usr/lib/xorg/Xorg
Thanks for the advice. Unfortunately I don't completely understand what you mean with the following: > Of course if some non trusted packages has also been installed, then goto ubuntu archive. For the moment I have purged xserver-xorg-video-intel without reinstalling it (since I've seen that it is optional). I cannot yet verify with certainty whether this solves the issue because I haven't found a way to reproduce it in a deterministic way. That said, after uninstalling xserver-xorg-video-intel, my virtual terminals are visible again (which I hadn't mentioned in the original post because I hadn't thought that this issue might be related). I will keep this configuration until I either run into the original issue again or you advice me to install the package again. In case this was a misconfiguration on my side (don't know why the optional package was installed): Sorry for filing a bug report.

The errors logged: kernel: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun kernel: [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun kernel: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun kernel: [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder B FIFO underrun so be sure to only use the intel driver from the (x)ubuntu archive. Purge xserver-xorg-video-intel (sudo apt-get purge ) then reinstall it. Of course if some non trusted packages has also been installed, then goto ubuntu archive. If the problem still persist after the above tweaks done, then check with a previous kernel. And the irq bios settings needs indeed to be checked. ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1625350 Title: High CPU usage of /usr/lib/xorg/Xorg Status in xorg package in Ubuntu: Incomplete Bug description: My laptop is running Xubuntu 16.04 and recently (don't know when exactly) started showing very sluggish display and input behavior: - Typed input lags several characters behind. - Mouse input is slow (e.g. when drag and dropping elements) - /user/lib/xorg/Xorg uses high percantage of CPU ressources (oftentimes 100%) Any help is appreciated.
