I'm using a Gigabyte GA-G41M-ES2L with onboard graphics and libreboot 20160907.
After installing libreboot and attempting to boot the Trisquel netinstall I can get to the point where I can select Install but at the point where the installer would actually be started the monitor changes to "input not supported." Another monitor says "input out of range."
Someone on the IRC channel had said they knew the cause but couldn't remember it. I'm filing a bug in case someone knows. And ideally it should be fixed.
I also tried using the Debian installer (9.6) for comparison and there's no difference. Stuck with a black screen saying "input not supported" or "input out of range" depending on the monitor plugged in.
Boot the trisquel netinstall, from text-mode in grub. on the linux kernel commandline (when booting the netinstall initramfs) use the parameter "fb=false" to boot in text mode.
install trisquel barebones without anything added
the first time you boot, do "sudo tasksel" and select your desktop.
this is how i installed trisquel on my own g41m
Jason, I've added a note about this to the documentation. See:
Thank you. fb=false does indeed fix this for me. I had already done another workaround where I removed the drive from the computer, used a SATA/USB adapter to connect the drive to one of my ThinkPads, did the install from there, then moved the drive back. Having this documented will be very helpful for the future.
The change has now been merged.
This is now officially fixed, so I'm closing this issue.
