Hi, It looks like there are some issues supporting your videocard in the latest kernel versions ( http://www.spinics.net/lists/intel-gfx/msg83618.html ) It could be very helpfull to collect some logs in order for the problem to be handled. Please follow the following guides:
https://wiki.ubuntu.com/Kernel/Bugs https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies As you can see from the links, as a last resort, at a minimum, your bug report should contain the output of the following commands: $ uname -a > uname-a.log $ cat /proc/version_signature > version.log $ dmesg > dmesg.log $ sudo lspci -vvnn > lspci-vvnn.log ** Package changed: ubuntu => linux-firmware (Ubuntu) ** Changed in: linux-firmware (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1545902 Title: Ubuntu 16.04 desktop bug Status in linux-firmware package in Ubuntu: Incomplete Bug description: Pardon me for the lack of information I am about to provide. I am fairly new to Ubuntu and am using the 16.04 in order to use wifi on my Dell XPS 13 9350. I believe I have found a bug related to the desktop or unity. This us d to happen with the earlier builds of 16.04 but as the development has increased the frequency has decreased. Basically what happens is the desktop has some severe crashes at startup. For one no icons appear (not even the top menu bar) and the only thing I can see if "wireless connection established" box and it rapidly appears on and off rapidly to no avail until I force shut off the computer. The only solution I have found is wiping the build and starting with the new daily live build. This doesn't happen all the time, in fact it happens randomly from what I can tell. No particular thing causes it... Again sorry for the lack of information.
