what hardware are you trying to install to?


I have an HP Probook 450 G1 with an i5-4200M and 8gb ram.

seems to be some sort of switchable graphics with an amd gpu (and the intel chip i suppose).
my next try would be to boot the installer with a 'nomodeset' option.
something like this:

basically you have to get to the linux boot command line and edit it, before you even boot the installer.

or is it a live system?

Nomodeset is one of the first things that i tried. I never heard of those acpi settings though. I'll try that as soon as i can.
Also, i tried turning off hybrid graphics in the BIOS already and it made no difference.

Where would i exactly insert the acpi arguments? I tried inserting them before and after the "quiet" arg. but it made no difference.

Those two video commands in the Ubuntu forum thread that set the resolution to 1280x1024 and the refresh to 60 look promising, since your "tearing" looks like the refresh rate is incorrect. I think you are meant to try one or the other.

Your next issue could be getting the wifi to work, judging by what the web searches turn up, since it doesn't look like that device is supported in the kernel.

you haven't even answered yet what graphics hardware you really have in there.
afaiu, these laptops always come in many different flavors, even under the same model number... the switchable amd/intel graphics is something that is likely to cause problems, so we (you!) need to know for sure.
also from now on whenever you try something someone suggested you have to document it fully, show exactly what you did and where you failed and also remember to UNDO what didn't work.

PS:
it would be good to get output from
Code: Select all
lspci -k
but i understand you can't even get that far.
or can you boot into a live session? debian or sth else?

Woah.
So, i tried running a live session like debiman suggested but the pc couldn't detect my bootable usb so i put my bios boot mode in to legacy mode, ran it and the installer menu looks fine. I have no "tearing" now.

I have a hunch that i'll quickly run into plenty more issues so i'll be reporting back.

Yes, the wi-fi is probably going to be an issue...do you have a wired connection to fall back on until it gets running?
