In Version: 51.0.2704.79-0ubuntu0.14.04.1.1121 I must disable hardware acceleration in Chrome otherwise the screen blanks (no backlight, no panel sync) when opening the settings menu. This problem occurred after the latest update from Mint (stable). Switching tty doesn't restore the display state.
I've put X.org, lspci, driver package version at http://pastebin.com/Lb9RAxyU What else can I do to help? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1554742 Title: in Ubuntu Trusty attempt to add a plugin in chromium-browser and the screen becomes black Status in chromium-browser package in Ubuntu: Confirmed Bug description: This happens in a laptop Dell Latitude D630. In a fresh install, updated, I added chromium-browser. After I hit the "A" key on the keyboard the screen became black and I could not get it to return back to normal. I added a screen, and with an additional screen it was the same (I checked that the bios was configured to allow a second screen - multimonitor mode). I launched firefox and typed some letters in the fields, search field and else, it worked perfectly. Between each operation I had to reboot using the SysRQ. Once I accessed from within ssh and it worked there, I could finish to copy some files prior backed up to another drive, and check the ongoing processes, then once all ok I was able to poweroff as root from within that ssh console. After several tries, and a moment while the laptop was shutdown, to avoid having it getting too hot, I tried again to configure this chromium-browser, and repeated the steps once, twice, three times again, rebooting with sysrq between each : when going to preferences > extensions > get more extensions > hit the "A" in the search field (wanted to install adblock), it resulted each time instantly in a black screen which would not return to X, nor allow getting a tty. Here are some log files, http://meets.free.fr/files/chromium-and-dell_d630/ and also the content of the console after I tried one last time to start chromium-browser, but this time from within the console: http://meets.free.fr/files/chromium-and-dell_d630/probl%C3%A8me-crash-gpu-chromium-browser.txt I don't know what to think about it.
