Computer not booting up properly after upgrade to 24.04

[brindle67]

Hi, i have a dual boot machine. I can still boot windows, but Ubuntu asks for login and password then it displays welcome to Ubuntu 24.04 and below documentation *management *support.
I am stuck now, help please

May I suggest that at the Grub boot menu you select Advanced options for Ubuntu and then select a Linux kernel that has recovery mode. That should load the Friendly Recovery menu. Select Resume. That will load to a login screen using an open source video driver instead of a proprietary video driver. If that brings you to a working desktop open Software & Updates>Additional Drivers tab and disable the proprietary video driver and continue using the open source video driver. Or, select a different proprietary video driver. You need to be connected to the internet to do this.

Regards

Hi thanks for your reply. I just tried that, it took me back to the same login screen, the only difference was a larger font. Brian

Did you install Ubuntu with encryption on the partition?

When did this problem start? After a Windows update, after an Ubuntu update?

Need more details to try and figure out what went wrong and when.

Thanks.

Hi it had been working fine, rarely used windows anyway. This happened after upgrading to the latest supported version yesterday. I am sure i did a partition when installing ubuntu. Thanks Brian

Sounds exactly the same as my problem, hope you can resolve it and let me know how.

When you get to the login screen try Ctrl+Alt+F3 to switch to another tty session and try logging in with your regular username and password. You may have to try a few F combos, 1-7.

Does that get you back to the desktop?

Hi, Yes I tried that f1-f7 no luck i am afraid, thanks Brian

How did you do this upgrade? Did you do an update/upgrade to the newer release or did you download the iso file, write it to a usb and install to the same partition(s)?

At the GRUB screen press e to edit the boot line for Ubuntu and find this line:

linux /boot/vmlinuz-<version> root=<UUID> ro quiet splash

Add nomodeset after quiet splash and then Ctrl+X to save temporarily and resume the boot process.

If this works and you can then get to the login screen and the desktop we are a step further.
