Boot artful desktop 20170817 under qemu with qxl 2. Wait until ubiquity-dm is displayed Expected result It boots Actual result It hangs on the splash screen and the dots below the Ubuntu logo are not blinking. If the option 'splash' is removed from the boot command line it boots successfully. It also boots successfully with -vga std but in this case the splash screen is in text mode not graphical unlike with the qxl driver. - It started with kernel 4.12. - It is still happening with kernel 4.13. - It only happens when booting from an ISO and not on an installed system. - It works with cirrus/vga, but not qxl - It works if nosplash is set (or splash removed from the boot command line) - It works on Xenial but not on Artful To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1711358/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
