Intel integrated GPU & Ubuntu


I have an HP Elitbook laptop, an i5 with 8 gigs of ram with Intel integrated graphics.
the install went fine and it works great on it, but there seems to be a glitch. Suddenly everything turns to like 16 bit color, the blues are green and whatnot and the only way to get out of is by changing refresh rate and reverting back. I was told it could be drivers, it also makes the font un-readable.
Is there a way to upgrade the drivers?

How old is the laptop? What is output pasted here (applying [ code ] tags, [ # ] icon above input window) from
Code:
inxi -GxxSza
sudo grep \(EE\) /var/log/Xorg.0.log
run from an Xterm or other virtual terminal (not from a vtty)?

IME you more likely have a problem with RAM or the display than software. If RAM is the problem, removing and reinstalling it could possibly solve the problem. If you boot a live Linux media other than Ubuntu or anything related it (e.g., don't use Linuxmint, Debian or Knoppix) would strongly indicate hardware fault.

You can try switching drivers, but I wouldn't expect it to help. Take a look in /var/log/Xorg.0.log for lots of lines that include intel(0) or modeset(0). If modeset(0) is absent or few compared to intel(0), remove xserver-xorg-video-intel and restart. If intel(0) is absent or few compared to modeset(0), check if xserver-xorg-video-intel is installed and if it is not, install it, then restart. Output from inxi should confirm whether the modesetting or the intel DDX is in use.

This laptop is about two or 3 years old. It's a business class HP.
It's a fresh install of Ubuntu 18.04 on 500 gig SSD. If I try and take a screenshot of the screen it doesn't capture it, only if I take a picture with my phone. It also does this weird thing like the screen rotates as if it's a mobile phone where the screen rotates with how you hold it. I tried this, (inxi -GxxSza
sudo grep \(EE\) /var/log/Xorg.0.log) all I got was no such file or directory. I tried this first (inxi -GxxSza) and the other second. I wish I could upload a picture of it. Running it from a thumb drive is a good idea. I'm gonna give that a try. I did run that laptop from a thumb drive before I installed it, and that didn't happen but then again I may have not let it run long enough to see it happen.

It may be that inxi was not installed on your system. Its current version can be had directly from its author here. Most distros only offer older versions. In 18.04 it's truly an antique, missing many options, and with many behaviors that have been superceded.

No such file /var/log/Xorg.0.log probably means you need to do this instead:
Code:
sudo grep \(EE\) ~/local/share/xorg/Xorg.0.log
Most (EE) lines in Xorg.0.log files are error reports, diagnostic aids to determine what failed. Any text file viewer can be used to look through it manually.

Try again substituting 1 or 9 or ? for 0. If neither of those work, open a file manager and go inspect /var/log/ and ~/.local/share/xorg/ to see if anything there resembles Xorg.?.log*. On anything you find you can use the pastebinit command to upload so we can take a look.
