Ubuntu + Gnome 3.14 = lots of crashes?

During an upgrade the other day, my Gnome Classic login started failing. The normal Gnome login worked, but that looks too much like Unity.  After trying to fix it for awhile, I just went ahead and upgraded Gnome from 3.12 to 3.14.

That fixed the login problem, but random apps would crash when I right-clicked or used the menu bar or hotkeys.  Turns out this is being caused by overlay-scrollbar.  If this is happening to you, try:

sudo apt-get purge overlay-scrollbar
That worked for me. Everything is working great now.

error: symbol 'grub_term_highlight_color' not found

I really need to consolidate my blogs. I wasn't sure whether to put this over at the server blog or the android blog or.... well, anyway, this one is generic enough for anything...

I had upgraded my laptop to Ubuntu 14.04 awhile ago -- but today my desktop had the auto-prompt asking me if I was ready, so I took the plunge.

Upon reboot, I got the dreaded grub recover error: symbol 'grub_term_highlight_color' not found.  This seems to be more common with people who dual boot, with grub auto-installing to the wrong drive.

Looking online, everyone said the easiest fix was to boot to a live DVD and reinstall grub.  Sure, no problem, I still have the bootable laptop.  Except it appears that it can't burn since upgrading to 14.04... odd...

well, to save everyone all the steps I took to troubleshoot this....

1. Use the BIOS to boot to the drive that had grub successfully installed
2. sudo dpkg-reconfigure grub-pc
select both drives (not any subpartitions)
3. reboot =)

Now if I can only figure out why my BDXL burner can no longer write discs...
Update: seems to be a Brasero problem. This works instead:
sudo apt-get install xfburn
