--- Comment #13 from Alexandre Demers alexandre.f.demers@gmail.com 2012-07-21 03:49:15 PDT --- It's been some time now. Since my initial report, I moved from Ubuntu to Arch. Today, it was officially announced Arch was moving to Grub2. So I updated my setup (I was using Grub legacy since my move to Arch). Suprise, this bug is still valide.
So I played around with grub default options. So GRUB_GFXMODE=auto works fine, but GRUB_GFXPAYLOAD_LINUX=keep triggers the bug. Removing the latest option makes everything runs smoothly.
I read bug 49262 and two things are common with my setup: we are both using a 69XX radeon card and we are both using a DVI-to-VGA adaptor. I'm wondering if the combination of card AND adaptor was the root of the problem. Before having this 6950 card, I was using an Radeon HD 3200 IGP without any adaptor and I had no problem.
I don't have any other monitor here and I don't have a DVI or HDMI input on my monitor, so I can't tell yet. But still, what would you suggest to try to help figure out what's going on? Any comment from Alex or Michel would be appreciated. I could have access to a different monitor if I ask for it.
