Run into the same problem, after several hibernation - wake-up cycles. Discovered recently than this bug is interconnected with corruption of active Xorg/Unity desktop GUI fonts family. In my case that was "Ubuntu*" fonts. NEW FIX: works for the active user session, without loosing active processes/apps: need to switch all themes' fonts to other (Verdana, etc.) than the active font set (Ubuntu *). These are Default, Document, Monospace, Window header font. One may accomplish this by using "unity-tweak-tool": $ sudo apt install unity-tweak-tool $ unity-tweak-tool Open Fonts section ("abc" icon); Change fonts; Then refresh desktop, may need to restart some windows; Also you may need to restart unity panel: initctl restart unity-panel-service Finding permanent fixes probably possible with fonts tweaking: https://wiki.ubuntu.com/Fonts Install alternative fonts, than do: sudo fc-cache -f -v However the bug could be related to runtime in-memory font cache corruption, and installing the alternative fonts will do nothing with the problem. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1573959 Title: On-screen text disappears after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-xenial/+bug/1573959/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
