[solved] lenovo thinkpad t60 blank screen after Syu

ponnuki · 2015-12-11 19:53:53

Just updated the system and now when I boot the screen goes black. I can still type (tested with sudo poweroff) so the system boot ok.

When adding nomodeset it boots fine.

I've tried :

although the video card is not intel. I've also added the Radeon :

https://wiki.archlinux.org/index.php/AT … _early_KMS

Enable early, to no avail.

Not too sure what to do next.

I am booting to the console, (no x), but X doesn't start either (when I try to start X when the computer has boot).

Any kick in the right direction would be awesome!

What packages did you update since the last time the computer started correctly?

ponnuki · 2015-12-11 20:38:30

It was a huge update (1gb down)... is there a way to generate a list of that file, I guess most file on the system got updated at that point.

So it's not intel graphics, what is it? ATI? What video driver do you use?

ponnuki · 2015-12-11 20:48:12

It's the Mobility Radeon x1300

I have the xf86-video-ati installed

In the file:

/var/log/pacman.log

It's possibly a backlight issue. Add the kernel parameter "radeon.backlight=1" to get the light back on (for example: "options radeon backlight=1" in "/etc/modprobe.d/radeon.conf").

If it's possible to barely see some text on the screen when booting by using a flashlight, it definitely is a backlight issue.

Here is my pacman log if that is any use:

I see there is a lot of driver installed - does that matter?

The external monitor plugged in works without having the nomodeset -

Trying your code on the next reboot.

You are right, it's a backlight issue, although the code you provided didn't work. I'll look into it.

Thanks for the kick in the right direction!

It's https://bugs.archlinux.org/task/46902
Install the 4.3.x kernel from [testing].

ponnuki · 2015-12-16 20:41:12

Thanks - I'll probably wait for it not to be in testing anymore, and use nomodeset for now
