Here is a list of fixes of some of the fixes I’ve applied to my Kubuntu install:
Picasa Doesn’t Recognize Videos
Under Linux, Picasa doesn’t handle video when it’s installed, this links shows how to make Picasa show video thumbnails and actually play movies. It only works for .MOV files though
Flash Crashing Chrome
Sometimes Chrome doesn’t handle flash very well ad you’ll get a variety of errors. Since Chrome comes bundled with it’s own version of Flash and you may have installed flash on your machine separately for Firefox or other browsers, it may get confused on which version of Flash to use.
Get Rid Of The Tree In Dolphin “Details” View
Kubuntu 12.04 annoyingly broke the details view in Dolphin. They show an expandable view in the pane rather than the folder contents.
Unix Style Copying
To get Unix style copying, where you simple select the text to copy it, go to the “Configure Klipper” dialog box and select the “Synchronize contents of the clipboard and the selection”
Slow And Unresponsive Kubuntu Desktop
When I first installed Kubuntu 12.04, my account was working just fine, but my wife’s account was acting very strange. It was very slow to react and most of the desktop would not respond. It turns out that my account worked because I had “Desktop Effects” turned on but I had the “Blur Effect” turned off in my account. I guess the “Blur Effect” has some issues with some graphics setups and mine was one of them. My wife’s account had desktop effects turned off and the upgrade turned it back on and “Blur Effect” evidently is one of the default effects.
automysqlbackup Throws LOCK TABLES Error
I have my system setup to email me when automysqlbackup backups happen. After I upgraded to 12.04, I started getting the following email:
Subject: ERRORS REPORTED: MySQL Backup error Log for lisa – 2012-10-29_07h40m
Body: mysqldump: Got error: 1142: SELECT,LOCK TABL command denied to user ‘debian-sys-maint’@’localhost’ for table ‘cond_instances’ when using LOCK TABLES
I found the solution here:
Logitech Wireless Keyboard Function Keys not working (Ctrl+Alt+F1…etc)
For the longest time I searched to try to figure out why Ctrl+Alt+F1 would not bring me into a terminal, in fact there was no visible response at all to any of the function keys on my Logitech Wireless keyboard. Then I finally realized for the 50th time that Logitech screwed up by requiring you to have the function mode key activated, which is not default, for the keyboard to send the codes for the function keys. For some stupid reason their stupid second functions are the default not <F1>, F2>, etc.
Ubuntu Doesn’t Recognize Serial Mice By Default
I have several infrared keyboards with integrated joysticks that I use for my MythTV boxes. Every time I reinstall the OS, I have to go through this rigmarole to get the joystick to control the mouse.
sudo apt-get install inputattach
sudo vi /etc/rc.local
Then I add this line to the file:
inputattach –microsoft /dev/ttyS0 #that’s a zero
If that still doesn’t work, in Kubuntu 12.04, navigate to System Settings->Input Devices->Keyboard Setings->Advanced. Then open up the branch that says Miscellaneous compatibility options and make sure Special keys (Ctrl+Alt+<key>) handled in a server is unchecked.
