Bug Description
I upgraded my NC10 netbook from Ubuntu Mate 16.04 to 17.04 (which worked okay) and then to 17.10. When starting up and automatically logging in I can see the right hand quarter of the screen but the left three quarters are mostly black with multicolour icons repeated across the top 3mm, a light grey bar below this 8mm high with a darker grey interruption just over half way across and two small horizontal white lines directly below this. The mouse pointer is displayed where ever it is positioned and the right hand menus work as expected. The computer is unusable in this condition.
Dropping to a terminal with Ctrl+Alt+F1 has the same screen corruption and the prompt is spread across multiple lines as a series of dots and dashes - completely unreadable. It seems the video driver is not working for this machine in this release. The previous release showed it was using the standard Intel open source drivers. Issue persists when PC rebooted. Power up shows Samsung boot screen then light grey screen with small dark grey border then the corruption described above grey background and green pattern (probably the boot image corrupted then clearing to corruption over black background then to the state described, i.e. mostly black with a bit of desk top and some corrupted stuff at top.
I can probably ssh in to this machine to grab logs as required so please let me know what I can do to help debug and get my laptop back working.
Computer is a Samsung NP-NC10 with 1GB RAM and Intel Atom CPU.
(Sorry I didn't find time to test the beta!!!)

I have found that putting the computer into sleep and waking up allows normal use, i.e. the display is normal and I can use it. The corruption returns when I power down the netbook or perform a reboot.
