I have a Lenovo Yoga 3 11 laptop with Ubuntu 15.04. When I plug the HDMI cable to my external monitor, the system goes into multi-monitor mode so I can use the laptop display and the external monitor and move windows across both displays.

When I unplug the HDMI cable, I would expect the display to return to single monitor mode (laptop display only). Instead, my external monitor goes blank (of course), but Ubuntu still thinks it's connected so I can still move windows off the edge of the screen. Why doesn't it automatically switch back?

It's able to detect on connection of HDMI and change modes, but not on disconnection. I know I can press the keyboard combination to cycle between modes, but this is more of a workaround.

I have a folder: /home/myuser/folderA

I want to give the www-data user write access to the above, while 'myuser' continues to have normal access (as it is myuser's home folder anyway).

Which commands do I need to use?

Note: I don't want www-data to have access to any other folders in /home/myuser/.

Thanks in advance.

I use sudo mkdir /var/lock/tt-rss/ to create this folder which a program called tiny rss needs. But if I reboot Ubuntu, the lock and tt-rss folders no longer exist. It's as if Ubuntu is treating them like temp folders.

I need /var/lock/tt-rss/ to be a permanent folder. How can I make it stay? I could probably do a startup entry, but that seems more of a workaround than a fix.

As the title suggests. Massive performance degradation?

And what technology does it use?

I don't mean importing manually, but true syncing?

If not, is there Ubuntu software which syncs gmail contacts separately, and then the above clients sync from that?

I have an NFS drive mapped in Ubuntu 11.10 using autofs which automatically mounts a drive on every boot. But if I use the Gnome Shell interface, a pop up notification keeps popping up from the bottom-centre of the screen saying the name of the mapped drive and an Eject option.

It pops up about every 5 minutes even though the NFS drive is already always mounted. Any way to stop this?

I've heard the Ubuntu Professional certification is no longer offered, although the course can be purchased here: http://shop.canonical.com/product_info.php?products_id=533

Is this true? After studying the course, is there no exam or certification given any more?

I'm running an unnecessarily complex script which looks similar to this command:

find /home/user/videos/*.avi -mtime +0 -exec mv -f {} "/home/nb/videos/1 day old" \;

And then I run the same command, but this time, from the "1 day old" folder into a "2 days old" folder. And some more commands keep repeating all the way up to 7 days old! So each day, files from the previous "X days old" folder move into the next day up's folder.

I'm basically trying to organise files automatically, running in cron, to move files older then X days into the correct folder. It's inefficient, but I do need this to happen. Is there any easier, more efficient way?

Once it gets to the 7 days old folder, I have the final command which removes files older than 7 days from that last folder.

Using Vinagre on Ubuntu 11.10, when I RDC into a remote Windows XP machine, I only get a 800x600 resolution on the remote display. I can't increase it on the Windows machine, it's stuck at 800x600. Any way to customise?

If I use Terminal Server Client on Ubuntu instead of Vinagre, I can adjust the res. Any way to fix for Vinagre?

I only want one of my accounts to make the mail indicator go blue when I get a new message, but I don't want it monitoring the second account I also have in Thunderbird. Possible?

Ubuntu 11.10 hides the close, min and max buttons in the top panel. Is there a way to bring all that back into the actual window and not in the panel?

Not just the buttons, but also the File, Edit menus back into their actual windows?

I've upgraded from 11.04 to 11.10 beta and installed Gnome Shell and logged on with the Gnome Shell session. My window title bars are orange like this:

Any way to fix?

I have Ubuntu Server 11.04, but it is headless (no monitor). The only way I want to be able to access it is remotely via SSH. But, sometimes, say after a power loss, when the server restarts, it will get stuck on the Grub boot menu, and it won't count down. It will just hang there waiting for me to choose the first boot entry. This means I have to go there and plug in a monitor and keyboard.

But I can't do that remotely. How can I force it to continue booting to boot entry 1 (default) regardless of power loss or whatever?

Have just installed nagios3 onto Ubuntu Server 10.04. A clean install. All plugins installed.

The nagios status map only has localhost and gateway discovered. Is there a way for it to scan our network, along with all Windows servers, routers, etc?

I can't find any automated way to do this.

Our network is a large school network so manual configuration is difficult.

When installing .deb files to install software, does its PPA also get installed into software sources?

I ask because if I find some software online which has a .deb download, I tend to look for its PPA, add it to my sources, then go through Synaptic to install the software. I do this because I want future updates for it.

But this is a longer process than installing .deb files with gdebi.

I have Totem player configured in its options to resume playback from the last position. But it does this for both video and audio files. But, I want it only for the video files so I can resume from where I left off, but not for music files. I want music files to start from the beginning always. Is there any way to force this?

Currently I have to use a separate music player, but I don't really want another player just for music.

I want one where it reduces the screen's brightness, either by time or on demand (I don't mind). I have onboard Intel graphics. I don't want it to be like Redshift where it changes the screen's hue.

I have an Ubuntu PC with ufw firewall (GUI version). I have added the preset Samba service, in and out, and even tried adding the ports manually (135-139, 445, UDP and TCP, in and out), but it still blocks samba.

I am trying to access a share on another PC on my LAN. If I disable ufw, it works fine. It must be still blocking something and I can't figure it out. Any ideas?

I'm on Ubuntu 11.04 beta 2.

In Gnome you can right click a menu item and add to desktop. Can't seem to find a just-as-simple alternative in Unity? Anyone know?

In the classic Gnome shell, you could add an Inhibit applet to prevent the computer going to sleep. This doesn't work with Unity. Is there an alternative and just easy way to prevent the computer temporarily following sleep power options? The Inhibit panel applet was as simple as a click.
