    Login Screen Flickering

    Hi pals, I upgraded my system (Kubuntu 16.04.3 LTS with KDE 5.8.8 LTS) with the option of proprietary drivers enabled in the software center and my Login screen has been flickering since. Sometimes when I type my password it just freezes and I have to switch to the shell then back to desktop environment to go to my desktop(Ctrl+Alt+F1 and Ctrl+Alt+F7). Below are the packages that were installed/upgraded

            Ok. You have an old ATI card. The proprietary drivers do not support your card. You can just use the default install. I don't see any evidence of any proprietary drivers installed, nor should you even have been able to install any.

            run these commands in the terminal

            Code:
            sudo apt update

sudo apt upgrade -s
            and paste the output

                Are you running any non standard repos or ppa's?

                Have you tried booting with an older kernel? You state your problems appeared with a recent update.

                  I'm not running any non-standard repos or ppas. How do you possibly boot with an older kernel? Will that rollback the changes? Can I perform another upgrade after that?

                    Open the file

                    /etc/default/grub

                    Edit the first few lines so they look like this:

                    Code:
                    GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
#GRUB_HIDDEN_TIMEOUT_QUIET=true
                    save it.

                    Then open a terminal and type

                    Code:
                    sudo update-grub
                    Now when you boot you should get a menu. Select advanced options, and you will have the possibility of booting all older kernels. Try one from the 4.10 series and see if your troubles go away.

                      Can I set which kernel to boot automatically when I switch on my computer or do I have to do this each time I switch on? Can I perform an update after that?

                          Hold the left shift key down during the boot up. That should present you with the grub menu

                            The issue is not about showing the grub menu but even after booting with an older kernel, there was no change

                              You can install as many kernels as you want. The first menu option is usually the newest kernel installed. Older kernels,?if you haven’t uninstalled them, will be listed in other options below the first and the “recovery” option.

                              IF you set grub so that it boots without showing grub you can force grub to show by holding down the left shift key during boot.
