black screen on Intel DesktopBoard D2500CC
 
Hi,

I need help,
when starting Slackware 64, via USB, it begins normal, boot -> I see boot messages, and than the screen goes black.

the bios from the board is configured to use VGA and only VGA, and I have a VGA monitor attached.

any idea what I could try?

(i trield to pass vga=normal and vga=791, they have the same effect)

Append
Code:

nomodeset
to the command line.

Appending nomodeset will disable the Intel Xorg driver. This may be OK for testing, but is not an option for normal usage. The better option would be to set the resolution and refreshrate of the monitor manually using the video= option (the vga= option is deprecated and useless for modern Linux video drivers), for example:
Code:

video=1024x768@60
to set up a resolution of 1024x768 pixel with a refreshrate of 60Hz.
Having said that, the Atom D2500 CPU on that mainboard features the PowerVR SGS545 video unit (relabeled by Intel to fit their HD naming scheme), which under Linux only has some 2D acceleration and almost no 3D acceleration functions. This doesn't matter for a server, but if you want to use this mainboard in a desktop system you are much better off with using Windows.

thanks for the tips

this worked video=1024x768@60 (with my monitor numbers)

this works also
video=LVDS-1:d
what is strange because LVDS is disabled in the bios, seems not to be real disabled

however, I can boot now :-)
makes me happy, the box will be a blackbox with some functionallity, and so I thought I can bring an other Slackware installation into a company environment.
(I need 'just' to optimize boot times, because there are some time requirements for reboot in the spec,hopefully this will work as I thought it should)
