display problems <Solved>

Post by florus » Sat Apr 28, 2018 6:18 am

My computer is becoming increasingly flaky and I cannot tell if it is a hardware of firmware/software problem. On opening a spreadsheet, it immediately scrolls rapidly sideways heading for column zz or whatever so that I cannot access or enter data. I cannot resize of move windows in firefox, thunderbird, Calc etc. except sporadically by a few pixels. They still minimize/maximize/restore as normal.
Modern computer, core i5 7500, integrated graphics, Mint 18.3 64bit cinnamon 3.6.7, Kernel 4.13.0-39.
I have changed mouse, keyboard, Kernel, re-installed Calc, tried Gnumeric, to no effect. Copied spreadsheets to laptop where they work perfectly.
Please advise on how to diagnose/solve problem.

Please generate an overview of your system like this:
- Launch a terminal window (this is how to launch a terminal window);
- make the terminal window full screen, to avoid chopped lines;
- Copy/paste this command into the terminal:

Code: Select all

inxi -Fxz
(if you type: the letter F is a capital letter)

Press Enter.

Copy/paste the output in your next message.

Try the latest kernel of the 4.15 series:
Update Manager - panel: View - Linux kernels

Afterwards, reboot.

Create a new user account, log in as that new user and change nothing at all in it. Does the problem happen in that new account as well?

Yes, still no change. Could it be a hardware issue?

Always possible, of course. Try booting the new Ubuntu 18.04:

Booted from live Mint 18.3 DVD - same problem. Unplugged everything and started testing peripherals one at a time. Problem item - receiver for wireless mouse. :oops: The problem had persisted when I switched original mouse off and used a different mouse, but was resolved by removing the receiver. Sorry for taking so much of your time, Pjotr, and many thanks for your help.
