System froze after plugging in HDMI. Now it won't boot


(This is a re-post from having posted in the wrong forum.)

I installed Debian Stretch on this PC several weeks ago and it's been running great until I tried plugging in an HDMI cable today. The PC froze. Now when I boot it up, it freezes (black screen).

I've tried purging video drivers and re-installing them, but to no avail.

I had been able to boot using "nomodeset" in grub, but I was stuck in low-res 4:3 instead of wide-screen. I tried removing/reinstalling xserver-xorg-video- drivers again and now that doesn't work either -- my display just flickers from graphics mode to text.

The only way I can boot now is into text-only mode.

Distro: Debian Stretch 4.9.0-4amd64
PC: HP Probook 4530s with Intel & Radeon video

lspci | grep "VGA":
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Seymour [Radeon HD 6400M/7400M Series]

Currently installed xserver-xorg-video* modules:
-ati 1:7.8.0-1+b1
-fbdev 1:0.4.4-1+b5
-intel 2:2.99.917+git20161206-1
-qxl 0.1.4+20161126git4d7160c-1
-radeon 1:7.8.0-1+b1
-vesa 1:2.3.4-1+b2
-vmware 1:13.2.1-1+b1

Short of re-installing from scratch, what can I do to get my video working again?
--Bryan

I've since re-installed xserver-xorg-video-fbdev and xserver-xorg-video-all


When it freezes I see things like the following on-screen:
vga_switcheroo: detected switching method \_SB_.PCI0.GFX0.ATPX handle
ATPX version 1, functions 0x00000003
...
i915 0000:00:02.0: fb0: inteldrmfb frame buffer device

HDMI

Are you still trying to connect with the HDMI connector?

No. I've got nothing plugged into either the HDMI or the VGA port. Just using my laptop screen.\

I've completely re-loaded Debian Stretch from scratch formatted HD and reloaded and copied my home directory from a backup ... and have the same issue as before -- I can boot up to a graphic login and run if I specify "nomodeset" in GRUB. But I'm stuck with 1024x768 on my wide (16:9) screen.

After the reload had the same issue I added firmware-linux and xserver-xorg-video-all packages.

One thing that seems so strange is that KNOPPIX 8.1 boots up great and works properly, but I've not been able to reconcile the video drivers it uses with what's available in Debian. I thought it was built on Debian, but it seems like the video support (and maybe more) is handled very differently.

Found a better work-around (than using nomodeset) for the time being. This is a hybrid video system -- Intel and Radeon. I disabled video switching in the BIOS, which apparently forces Intel video support. Now it boots up fine and I get my higher resolution screen.

Still, if anyone has any suggestions on using this old ATI Radeon card, I'll give it a try.
(I also can't explain why the system had been working and then froze and stopped booting up properly.)
