Screen flicker after installing antiX-17

[Member pietebr]

Hi! I tried to install antiX-19 on my HP Compaq NC8430 laptop with Ati Mobility X1600, but it keeps freezing after install (the alternative kernel lasts longer). So I tried antiX-17, but booting on install, the screen starts to flicker as soon as the resolution changes to native (1600×1050). The flickering didn’t occur on antiX-19, so I gather it may have to do with the kernel (flickers with the alternative kernel, too).

Has anyone faced this issue, and if so, how did they resolve it? I really like antiX, am using it on my current notebook, but just would like to give a new life to the old one, too.

The strange thing is that both live versions work fine, although I didn’t use them beyond the install. (Actually, antiX-19 didn’t boot without choosing safe video mode, got stuck on waiting for /dev to be fully populated…)

Try antiX 17 live version again and execute:
inxi -Gxxx

Save the output in a file to you Hard Drive (or copy and paste it on pastebin or some other place so you can access it again later).

Now, back again in you antiX 17 installation with the flickering screen, runn the same command again
inxi -Gxxx

Paste both (referencing which is which) in your next post. We will try to figure out with this information if anything can be done.

What if I told you than on the third boot that I made to get the output of the inxi command, the flickering was gone? 😉

And the fourth boot was flicker-free, too. I wonder what happened…

Anyway, here are the outputs, if I get flickering, for sure I will return here:

Hi! I hadn’t booted into antiX, booted once, everything ok, did a reboot and the flicker returned…

The output of inxi -Gxxx is the same.

This could lead to a wild chase, but it must be related to the kernel.
See this bug entry for Ubuntu for the same video card:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1791312
See the attached video. Is your case the same?

Maybe updating to a 4.19 kernel (antiX or debian, what ever you prefer) as reported by the other user may help.
Also, maybe a specific xorg vsync configuration may help. I have no experience with that, though.

Worst case scenario is having to compile your own kernel with a specific radeon.ko module

Thanks, two boots with 4.19 kernel and without flicker…
