No video signal after Grub

foobar42 · 2014-10-21 12:29:43

Hi everyone,

my graphics card is ATI HD7850 and I am using the open source radeon driver.

I ran this setup for about a year without any flaws until I installed an SSD into my system. I copied the root (/) from my HDD to the SSD following this guide: https://wiki.archlinux.org/index.php/Fu … with_rsync

After I edited the files in /etc/fstab and /boot/grub/grub.cfg, and configured another boot order in my BIOS, I started Arch and everything ran fine. I then installed Windows to the SSD on another partition which also runs fine.

But when I tried to run Arch again I did not get a video signal right after Grub (monitor said no signal found). After hitting reset it worked again.

Now I need to try to boot Arch about 5 times until it works. Even a USB stick with a fresh Arch ISO from the download section fails to boot in about 4 of 5 attempts.

Windows starts without any errors and I can play video games just fine, so I don't think my graphics card is broken.

Does anybody have an idea what might be wrong? I am totally lost here.

Things I tried to do:
- Rebuild boot image with mkinitcpio
- Tried to start without dynamic power management for my graphics card

KAozdl,

Saddly, foobar42 has not visited the forums in the last couple years. I am going to close this old topic and invite you to open a new topic which you will own. If you believe this thread to be relevant, go ahead and use BBcode url tags to link back to this thread.

Thanks.
