Unity buttons off left side of screen with 9/4/2015 update

[jerrylamos]

Since update unity buttons no longer visible, off the left of the screen. Settings Hide is off.
A number of screen images are horizontally barred even the settings wallpaper choices and the full screen, exit buttons on the window frame.
Terminal text will be horizontally barred, then clean up when screenshot is selected, then barred again after.

Does this issue go away if you boot back into the prior kernel?

[jerrylamos (jerrylamos)]

I typically use 1280 x 720 resolution easier for me to read.
That's a resolution where after last week's update the screen is shifted left, black margin on the right, and unity buttons fall off the left. Hide is off.
If I change to 1368 x 768 the unity buttons are visible.
The monitor will actually support 1920 x 1080 but I'd have to use a magnifying glass.

Looks like X doesn't support resolutions it used to for this hardware.
Wily Display options in settings:
1920 x 1080
1360 x 768
1280 x 960
1280 x 720 my preferred for readability
1024 x 768
800 x 600

If I shift back to a Wily a month old works with that level kernel.
Looks like X + linux has dropped support of 1280 x 720.

BTW, at the moment this is 14.04 LTS. Runs great. I'll shift back to doing battle with Wily later today.

jerrylamos, as per http://support.lenovo.com/us/en/products/desktops-and-all-in-ones/thinkcentre-m-series-desktops/thinkcentre-m58p an update to your computer's buggy and outdated BIOS is available (5CKT77A). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.

Once the BIOS is updated, and the information above is provided, then please mark this report Status Confirmed.

Thank you for your understanding.
