new kernal, 3.19.0-26, hangs

[geezer]

If I boot 3.19.0-26 from the latest update, on boot it displays the Kubuntu logo, then a black screen and hangs.

I have to press Ins or F2 to bring up the options and boot 3.19.0-25. That version will boot fine.

Is anybody else having problems with the newest kernal update, 3.19.0-26, hanging on boot?

It boots just fine here. Are you using any proprietary graphics drivers?

No, just checked, working fine on both my Vivid installs, using the Nvidia 304 driver.

I am having that exact problem here! Udated yesterday and now I'm using a LiveCD while trying to fix it... Still worse, for some reason I have no input from keyboard while booting and I cannot choose any option. Not even when the LiveCD menu appears. Why can that be?
Is there any way to somehow make the system return to the previous kernel from the LiveCD?
Boy, it's been all joy for me since 15.04...

OK, I just plug the keyboard off and on again and it's working fine (?). I got to GRUB and I booted 3.19.0-25 with no problems.
This is the first time I have a non-working kernel... I'll read around a little and see what's to do.
By the way, I'm using the fglrx AMD video driver for a Cedar Radeon card (according to System Settings). Does that have anything to do with the new kernel problem then?
Thanks!

Yeah maybe... When I was running Fedora, sometimes the Nvidia driver wouldn't update with a kernel update even when using dkms. The solution then was to drop to a console and run a manual update.

Try pressing Ctrl + Alt + F2, logging in and running

sudo apt-get update && sudo apt-get upgrade
sudo reboot

I have never encountered this problem in the Debian family so I don't know if this will work.

Mmm... So I guess I just uninstall the new kernel (3.19.0-26) via Synaptic while using the previous one (3.19.0-25), then update GRUB and that will be it, right? Or should I do anything else before rebooting?

[Fernando]

Well, no need to roll back to 3.19.0-25 kernel in the end. Just as I was about to do it, an update notification popped up for, among other things, the video driver. I just tried and kernel 3.19.0-26 seems to work perfect.
Thanks!

This is interesting. I am running the AMD graphics card also and the fglrx driver. I haven't received any mention of an update. Will have to check that out with the Catalyst Control Center.

Okay - I booted the muon package manager and uninstalled fglrx (first I opened the systems settings and then the driver manager and switched from fglrx to X.org display driver), then installed fglrx again, then rebooted.

3.19.0.26 booted up fine. So I guess there was some kind of incompatability between the kernal and the version of fglrx I was running.
