Boot your system using a "live DVD" or (preferably) a “Live Demo” image on a USB drive

Open a shell window and become root: sudo su

Create a directory: mkdir /x

You need to know which drive partition holds the target system, i.e. the Linux system you want to boot. For clarity, let’s discuss things using the shell variables $partition and $drive. An example might be: partition=/dev/sda6 ; drive=/dev/sda

If you happen to know, based on experience, where the target system lives, define $partition and $drive accordingly, and skip to step 8. If you need to figure it out, proceed as follows:

    Get a list of disk drives: cd /dev/disk/by-label; ls -al

    With any luck, you will see something like this:

    drwxr-xr-x 2 root root 200 Mar 26 07:59 .
    drwxr-xr-x 6 root root 120 Mar 26 08:00 ..
    lrwxrwxrwx 1 root root  10 Mar 26 08:00 emu -> ../../sda9
    lrwxrwxrwx 1 root root  10 Mar 26 08:00 linux-root -> ../../sda5
    lrwxrwxrwx 1 root root  11 Mar 26 08:00 lnx -> ../../sda11
    lrwxrwxrwx 1 root root  11 Mar 26 08:00 more -> ../../sda10
    lrwxrwxrwx 1 root root  10 Mar 26 08:00 SERVICEV003 -> ../../sda1
    lrwxrwxrwx 1 root root  10 Mar 26 08:00 SW_Preload -> ../../sda2
    lrwxrwxrwx 1 root root  10 Mar 26 08:00 usrsrc -> ../../sda7

    If necessary, you can get additional information from cfdisk /dev/sda. This has the advantage of showing the partition size, along with the partition-type for each partition.
    Identify which partition(s) might plausibly hold the target system’s root directory. In the example above, linux-root is almost certainly the right answer, but lnx is a semi-plausible alternative.
    To make sure, mount each plausible partition and take a look at it.

       mount /dev/sda11 /x
       ls -al /x/boot/vm*
       ls: cannot access /x/boot/vm*: No such file or directory

    That tells us that sda11 is definitely not the right answer. So let’s try again:

       umount /x            # unmount previous hypothesis

       mount /dev/sda5 /x
       ls -al /x/boot/vm*
      -rw-r--r-- 1 root root 4275712 May 30  2013 /boot/vmlinuz-
      -rw-r--r-- 1 root root 4678720 Aug 25  2013 /boot/vmlinuz-3.10.9
      -rw-r--r-- 1 root root 4599824 Mar 23 18:45 /boot/vmlinuz-3.11.3+
      -rw-r--r-- 1 root root 4599824 Mar 23 18:43 /boot/vmlinuz-3.11.3+.old

When you find the desired partition, leave it mounted on the mountpoint /x.

Define $partition and $drive accordingly. Example: partition=/dev/sda5 drive=/dev/sda.

If not already mounted: mount $partition /x

Reinstall grub: grub-install --root-directory=/x $drive

Beware: You want to install grub on the drive (e.g. /dev/sda). If you install it on the partition (e.g. /dev/sda6), the grub-install program won’t complain, but the results won’t be what you wanted.

For me the solution was to change my compositor I switched to compton. You can get is link:here. Even without a config file it will work fine but write a config file that works for you and it will work best.

I had the same problem and I was able to solve it by changing the video output module to x-video-output(XCB). You can do so by going to tools>preferences>All>Video>Output modules and choosing what is suitable for you then save.
