Install Buster on w530 hangs with two blue dots

Postby stkris » 2020-08-24 16:54

The Thinkpad w530 has a NVIDIA/Intel dual graphics card.

So in BIOS I've tried all 3 combos - Intel, Nvidia and Optimus. Does not change anything.

I boot from USB stick with the minimal netinstall. I get the menu. Both Graphical and non-graphical install instantly give me a black 1cm strip on top of my screen. Where I can see 2 blue dots. Or occasionally lots of multicolored dots.

So I assume this is a UI-driver issue. Try to edit the grub to include

Code: Select all
nomodeset nouveau.modeset=0


but that did not change anything.

I have problems debugging this since

Code: Select all
You can access this console by pressing Left Alt+F4 (hold the left Alt key while pressing the F4 function key); get back to the main installer process with Left Alt+F1. These messages can also be found in /var/log/syslog . After installation, this log is copied to /var/log/installer/syslog on your new system.


this does not work so I cannot check the log.

Basically I'm stuck.

It's an old laptop for a hobby project so no biggie. But I really would like to learn how to debug and work around this issue.

Have you tried any other Debian derivatives to see if their Live sessions can boot to a GUI, and if so, what video drivers are in use?

I'm working on it. Only have slow, unreliable and expensive mobile internet where I live - no broadband luxuries. So it's a slow process. Trying Ubuntu first.

Any other derivatives in particular I should try?
