Failures on TopJoy Falcon #15

Closed tolidano closed 5 years ago

tolidano commented 5 years ago

I have just installed the TopJoy Falcon ISO (via the “try” and then “install” option on a USB Stick). I allocated a 30GB partition for Ubuntu but kept Windows. After install, it asked me to reboot, which I did. It did not boot GRUB, but instead Windows. I had to go into the BIOS and swap the UEFI Boot Order so the Ubuntu partition came first. I rebooted and saw a normal sized (not native resolution) GRUB menu (rotated 90 degrees). Then, I selected Ubuntu. The screen is completely garbled (lots of very thin slices). I used basic reasoning to shut it down and start it again. This time the GRUB menu was at native resolution (the text was much much smaller). I again selected Ubuntu. Same issue. Start over, this time selected recovery mode (always on the 5 kernel) Now got the pink menu with choices to drop to root or resume. I selected resume. Now I had a native resolution screen, rotated 90 degrees. I logged in, and attempted to rotate using the system displays menu or the xrandr but both allowed no rotation to occur (and xrandr had an error about gamma detection). I restarted again and tried normal, same garbled screen for both login and the desktop.

What can I write at the root prompt to provide more info? What can I do to fix it? Should I just try installing again?

Ok, more information: I reinstalled from scratch but kept WiFi off. It worked fine. Multiple restarts later, all seems ok. But then I went to software center and updated everything. Upon reboot, it’s back to a garbled screen.

So something has been broken by running a software update. If I could have some info on what might have broken the display, I can attempt to restore it.

Any assistance greatly appreciated.

Ok more info: it installed the 5.0.0-23-generic kernel and made it the default. This kernel does not have the appropriate modifications made by the script here (I’m guessing) and so it fails.

I modified /etc/default/grub to set the GRUB_DEFAULT to “1>2” which picks the 2nd and then 3rd item which should be the valid 4.18 kernel that it installs with.

I tried removing the kernel but dpkg said it wasn’t even there to begin with. This solutions works fine for me, I can boot to windows when necessary but also by default start the 4.18 kernel of Ubuntu which works very well.

Full boot in 20 seconds is pretty stellar.

Ubuntu MATE 19.10 will be released on October 17th 2019 and I will have a bespoke image for the TopJoy Falcon. I just tested a pre-release image and am happy to report everything is working correctly :+1:
