Ubuntu 24.04 - some problems

Hello. I installed Ubuntu Mate 24 instead of 22 on 2 PCs. Although it's alpha It's quite stable , but I get some problems. I do clean install UEFI mode dual boot with Win10.

  1. Software Boutique and Welcome don't work. Solved by uninstall as I not use them.

  2. update-grub not update timeout
    I have GRUB_TIMEOUT=5 in etc/default/grub
    But Grub always waits about 30s

  3. broken locale (mixed English interface) Probably after cleaning with Bleachbit
    Only on one PC. On second PC I fixed it but don't remember how :slight_smile:

  4. Most important:
    I know I need Nvidia driver 390. but driver installer don't show any drivers.
    I tried this ppa, Proprietary GPU Drivers : “Graphics Drivers” team
    but adding ppa broke sources chooser & driver installer

  • sudo add-apt-repository ppa:graphics-drivers/ppa
  • sudo apt update
  • after sudo apt install I get nvidia-graphics-drivers-390 not found
  • running software-properties-gtk gives error
Traceback (most recent call last):
  File "/usr/bin/software-properties-gtk", line 100, in <module>
    app = SoftwarePropertiesGtk(datadir=options.data_dir, options=options, file=file)
  File "/usr/lib/python3/dist-packages/softwareproperties/gtk/SoftwarePropertiesGtk.py", line 163, in __init__
    SoftwareProperties.__init__(self, options=options, datadir=datadir,
  File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 109, in __init__
  File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 437, in backup_sourceslist
    source_bkp = SourceEntry(line=source.line,file=source.file)
  File "/usr/lib/python3/dist-packages/aptsources/sourceslist.py", line 509, in __init__
    raise ValueError("Classic SourceEntry cannot be written to .sources file")
ValueError: Classic SourceEntry cannot be written to .sources file

Program is working again after delete file
glxinfo | grep OpenGL shows me:
OpenGL vendor string: Mesa.
Should't it be something like Nvidia or Nouveau?
Is any trick for install this driver or should I return to Ubuntu 22 on PC with older Nvidia?

  1. Second most important: Firefox not update. I disabled auto-updates, because I'd like to always make Timeshift backup before update. And Firefox (snap version) is still in 123 version (newest is 124)
    Solved: Firefox update with sudo snap refresh firefox
