As per title, I'm searching if there is something similar to OSX's Quick Look or Gnome's Gloobus Preview for KDE: searching Google brought me to some KDE's brainstorms, but nothing more.
Also to Duong Pham website, where he suggest to add a Dolphin sevice menu item installing Gloobus Preview and then create the .desktop file: this is not a solution, because you have to right click and select "preview", rather than just press SPACE.
Any idea?
I have two monitors working just right with nvidia driver.
There are times, however, where I want to have just one monitor and other times where I need two: I must open NVidia XServer Settings, go to the XServer Display Configuration and change the second monitor from TwinView to Disabled (and vice-versa).
Is there a way to just toggle that? For example having a shortcut on desktop and/or on the Unity dock? Maybe is there a way to configure a keyboard shortcut to achieve this?
P.s.: I'm using 11.04 with Unity and, of course, Compiz.
After the installation of electricsheep, the screensaver won't work: it starts fading to black then, when it should display the screensaver, it suddenly goes back to desktop. I read that disabling compiz should fix this behaviour but I don't want to go 2d-unity. I'm using Natty. Any suggestion?
After shutdown I notice that both the USB hub and the external USB drive remain active (lights on): the next time I try to boot the system hang after grub and I have to do a hard reboot. After that the system boots fine, until the next shutdown/boot cycle.
Ideas on how to troubleshoot/resolve the issue?
EDIT: The USB hard drive is powered by an adapter, while the hub is self powered; it's a dual-boot machine, with Windows XP on another partition and with Win there's no such a problem.
EDIT #2: It's a PC, and the USB devices remain active after the PC's shtudown: I mean, when the pc is completely off, not standby, not hibernated and not suspended. After that the CPU, PSU, GPU and the various fans are completely quiet.
EDIT #3: The problem occurs also if a SD card is in the reader at boot time.
There's a way to safely try KDE on top of an Ubuntu installation, keeping the possibility to revert the changes in case I dislike how it runs?
I used to set the mouse scroll to hide the windows when scrolling on the title bar: alas, I can't remember how I did that...
Can you please tell me how to achieve it?
As per title, I wish to know if I can, after a successful 32bit setup and consequent software installations, update to a 64bit version.
I know how to partition (actually one of the solutions is to set /, /etc, /home, /var/www, and /opt as separate partitions) and I know that a clean install is way better than a dirty one, yet I would like to know if/how it's possible to do that.
For the second time I experienced a strange behaviour on my Ubuntu 10.04 box: some files are disappearing.
The first time happened with a NTFS partition on an external usb disk: "disk utility" told me that it had bad sectors in it and thus it was unreadable but, after a reformat of the disk, it was recognized succesfully.
The last time it happened with a ext4 partition: my home folder was almost completely wiped out; fortunately enough I use to store backups of my files, so I restored them but I can't figure out why I'm encountering those kind of situations.
So I assume that the problem is not really a matter of bad sectors (two different hard disks, that after the restore are working fine).
What am I supposed to do in order to debug/resolve the issue?
NOTE: the OS is a former Ubuntu Studio 9.10, upgraded to 10.04.
