Comment (by cdesai):
* First boot without any special settings: results in black screen
Yes.
* Black screen is caused by wrong video mode choice (have you checked
this, which mode is chosen?)
I couldn't find the mode from a quick look in the bootloader, and couldn't
save it as I didn't have a FAT partition / another drive at that time,
sory.
* Checking "use failsafe video mode" gets system to work (no need to force
a video mode?)
I had to force Standard VG
* Forcing a 4:3 video mode + "use failsafe video mode" works?
I tried a few and they didn't work.
* Once booted this way, setting a video mode in preferences > screen and
rebooting normally (with the intel driver), does that work?
There were no 16:9 options there.
* After having set a video mode this way and rebooting, can you go to
screen preferences again and set the native resolution? Does it work then?
Like above, no 16:9 options.
* Does the panic happen only in 'show debug on screen' mode?
Yes.
I have had a hardware configuration, got a new graphics card (AMD R9 270),
and that worked well - same build, booted off live usb, it picked
1600x900@60 and worked just fine.
Unfortunately, this also means I won't be able to test the older
configuration now.
