Just for the record My Dell Latitude E7440 (Intel graphics card only) experiences the same problem with Xubuntu 16.04 Xenial Xerus (issue was not present in Xubuntu 12.04, and I didn't tried intermediate versions) I tried several workarounds but none seems to work this far.
I updated to Kernell 4.8.0-29-generic with # apt-get install linux-image-4.8.0-29-generic That was the latest update available in the repo at the date. It installed successfully. After reboot the Xorg process was using >80% CPU and the computer was even more sluggish than a Windows Vista running in an Intel 80386 (5 seconds delay for a typed char to appear on screen in console). There is no need to be an Ubuntu expert to conclude that just updating the Kernel is not enough to solve the problem. Maybe I'm missing some extra configuration or also the X-Server/lightdm daemon must be updated accordingly. Also I'm differentiating Xubuntu from legacy Ubuntu because it affects Xfce and Unity. Cheers! ** Attachment added: "How desktop looks like after resume from suspended." https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1573959/+attachment/4828906/+files/bug.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1573959 Title: On-screen text disappears after suspend Status in xserver-xorg-video-intel package in Ubuntu: Confirmed Bug description: After resuming from a suspend, almost all text on screen is not visible. This includes menu items, text in all three boxes (list of folders, list of e-mails, e-mail body) in Thunderbird (with the curious exception of "ffl" in the File menu), top menu in Chromium (but not the menu obtained by pressing the hamburger button), and the menus produced by clicking items in the system tray. Also, the apport dialog had no text except for a few capital letters. ADDITIONAL INFORMATION: * initctl restart unity-panel-service restarts the panel, but the text is still missing * suspend and resume does not fix the issue * Logging out fixes the issue * Other affected applications: ** Chromium file select dialog ** Terminal (entire window) ** ttys 1-6 (Ctrl+Alt+F1, etc.) ** Document viewer (menus) ** Software Updater ** Rhythmbox ** The dialog that appears when you take a screenshot with Ctrl+Alt+PrtSc ** ubuntu-bug ** Nautilus ** LibreOffice Calc (spreadsheet text contents) ** Firefox * Unity dash is not affected. * Skype is not affected. * Mousing over a button in a dialog correctly shows the text.
