Simón's questions

I've been using Ubuntu 20.04 in a very old computer (with a very old nVidia card) for a long time without problems, until it was automatically updated to Kernel version 5.13.

I don't know what, but something is definitely broken in the Kernel 5.13 that causes several issues:

• nVidia card not working correctly (can't login to desktop, screen stays completely blank).
• form time to time the filesystem automatically goes into read-only mode and the only solution is to reboot the machine.

I didn't spend much time looking for solutions to those issues, because I still had the option to boot using Kernel 5.8, which worked perfectly.

But now Kernel 5.8 disappeared from Grub's list, and it only allows me to choose between 5.13 versions.

How can I bring Kernel 5.8 back and prevent automatic upgrades from removing it?

I have an old Dell Latitude E6330 laptop, it has this logo at boot time:

I have dual boot, and when Windows boots, it correctly displays the large DELL circle logo.

But when Ubuntu boots, after the grub menu, it chooses the small Energy icon instead.

So I have not one but several questions related to this:

• Why is Plymouth displaying the wrong image?
• How does Ubuntu pick the logo image from EFI?
• Can I help it choose the correct logo image to display during the boot process?
• Or even better: can I customize it?

I re-formatted a FAT32 partition as NTFS from Windows Server, on a dual-boot machine, and now I can't get into to Ubuntu.

Windows won't allow me to re-format it back to FAT32. And I don't have another way to boot!

I did some research and understand that the problem is the /etc/fstab file saying that the /data partition is vfat.

I can only get to grub and see its contents. So I was looking for a way to edit this file from grub. I understand me that this is not possible.

So I'm looking to get into Recovery Mode. I can make it to the Recovery Menu, but as soon as I hit one of the arrow keys (to select the Drop to root shell prompt option) I get:

Login incorrect

Give root password for maintenance
(or press Control-D to continue):

Obviously, this is Ubuntu, and I don't have a root password!

I think I need to find a way to fix the Recovery Menu, but I'm losing hope.

I have different drives; SSD, HDD, USB, eBook readers, and phones, usually show up with particular icon identifying the type of device.

I would like to understand how does Launcher or Nautilus get to differentiate storage device types and to assign a custom icon; if that's done at the application level, or is something at a lower OS level that may affect this.

I wonder if it is possible to set a specific icon to different partitions on the same drive, or to have a Kindle showing up with an icon that differentiates it from a normal pen-drive.
