From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

(OLD) Tablet Boots to Black Screen After Attempted Debian Install (lemmy.fish)

This is an old post, I plan on making a new one with updated details.

I was installing Debian on my Getac F100-G2, and I booted to the live usb perfectly fine. I tested everything and it seemed to work great, except for one time I got logged out randomly. I installed it(overwriting windows) and it completed with no error. When I rebooted, it booted to a black screen and did not provide any error message. I've tried booting to the same installation media as well, and it does the exact same. I've switched between legacy boot and uefi, which has been an issue in the past with debian. I have also tried booting from a pureos live usb and that hasn't worked either. Getac devices are for enterprise use more than person, and rather poorly documented, so any help is appreciated!********___

So the good news is you're probably not bricked.

I've had similar, and had to work through getting my bios into the right state to get the screen to load, and then escaping grub into a grub recovery shell to debug.

Edit: Do you have access to an alternate/external monitor? I would want to try another monitor, just to rule out a hardware failure, too.

I have tried to use my tv but it showed a black screen as well, the bios shows up and works fine so I'd imagine its not hardware related.

Yeah. It's not hardware, then.

I would try searching "black screen " with any name and version number you can figure out about your bios, next.

If you can get it back to booting from install media, I would do a full reinstall.

There's recovery layers (such as grub shell) that ought to kick in if this was just a display config issue, so I'm thinking corrupted install files is more likely.

Also, do a careful check through your various BIOS settings - search each one with "Debian 12 ", to find out if they work with Debian 12, or need adjusted. Debian 12 supports most boot security features, that I have encountered, but I believe there's still a couple out there that have to be turned off.

I suspect your next practical goal will be to get the (presumably failed) bootloader install replaced.

Edit: Tried to add a lot of specific thoughts as search term leads.

I'm going to re-install windows to make sure the tablet is functional, and then repeat the process. The weird part is any live linux usb doesn't work either. It is a strange issue, thanks for your help.

thanks for your help.

Sure thing. Feel free to keep us updated. I hate to see anyone have to use Windows longer than they want to.

The mystery is why even windows won't boot now. I might tell getac about this and ask for help, unfortunately this isn't under warranty so I won't be getting a replacement.
