Skippy le Grand Gourou, thank you for reporting this and helping make Ubuntu better.
Could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel- ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, Y, and Z are numbers corresponding to the kernel version. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Package changed: xorg (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1501421 Title: Ubuntu 14.04 displays strange characters Status in linux package in Ubuntu: Incomplete Bug description: Quite often, when "opening" the laptop after it has been "closed" for a while, the display is completely messed up, i.e. most characters are corrupted with alien-like characters. Attached is an explicit screenshot of Thunderbird tabs (the first tab should read "Courrier entrant", the second line "Relever ; Écrire ; ? ; Adresses ; Étiquettes ; Filtre rapide", etc.), but most applications (Firefox, gnome-terminal, LibreOffice, Gnumeric, windows titles and menus, right-click menus, etc.) are affected. Some of these issues (e.g. tabs) can be fixed by hovering them with the cursor, but not all.
