  • As I upgraded to Ubuntu 13.10, I noticed that I lost the option to turn off the color when printing.

    Looking around all the available options, no one to make it black and white (although the old option was saying something like: Color: Off; it was somewhat weird.)

    Now that option is completely gone. There is no way for me to turn off my HP Printer color when I am in Acrobate or LibreOffice. I searched on the Internet to see whether that was just HP trying to get you to use colors on your printer or whether the option was available... somewhere else.

    Indeed, I had to go to the System ...

  • Argh! It happened again and I just couldn't remember the key strokes. And it's hard to find the docs about it so I write my own right here. What's all that about?!

    In X11, when you inadvertendly hit "Num Lock" on your keypad while you're holding the Shift key down, you actually turn ON this special Keypad feature: the Keypad becomes a mouse!

    Hit Shift + NumLock again, and you get out of that mode (i.e. a toggle)

  • I found it a pain to see the Firefox window gets closed when I click the close button of the last tab.

    When I use that same feature in SeaMonkey, it does not close the main window, instead it makes the tab empty.

    Today I thought that maybe they had a flag in there to decide whether the main window should be closed or not and indeed they have:

    browser.tabs.closeWindowWithLastTab

    So all you have to do is change this flag to 'false' (the default in FF being true now) and closing the last tab won't close the window!

    To change your Firefox configuration use:  about:config

    To ...

  • No Panels at All

    The Gnome X11 environment comes with a system called Panel.

    Gnome panels are bars where the system include menus, icons, the date, statistics, etc.

    Without the bar, it is a tad bit complicated to run programs and do all sorts of things (like switching between windows.)

    If the panel software itself did not start properly or crashed, you may restart it with the following command:

       gnome-panel
    

    In case, however, the problem was that I wanted to hid the two panels I use (the default top and bottom panels.)

    Panel Properties sample screenshot.

    So I right clicked and selected the option properties. ...

  • Okay, it has been a little while now, but each time I just have to search forever to find out how to create a multi-level numbering list.

    By default, a list will appear as this:

    1. Chapter

        1. Section

            1. Sub-Section

    Which may work for you, but in many cases you want to have all the list numbers appearing in your section and sub-sections as in:

    1. Chapter

        1.1 Section

            1.1.1 Sub-Section

    Okay, so that in itself it actually very easy, but it used to be that you could ...

  • I love Linux and use Ubuntu, but all of a sudden you don't have support for Gnome. Instead they now force you to use Unity. It's probably a good idea to go with the flow because trying to maintain Gnome is probably a hell of a lot of work so...

    I have to have a few things in my window system:

    1) Menus MUST be attached to the window I'm using. I don't like the Macintosh way. Sorry. To remove the menus from the top, run the following command:

    sudo apt-get remove appmenu-gtk appmenu-gtk3 appmenu-qt

  • Today I got a new video card because it looks like the old one I had was going bad. I hope that was not my KVM, although we'll see when it gets hot again, whether the video goes bouncy again or not... If not, then the old card is good for the trash (although it works in console mode just fine!)

    So I got a new card. My old one was a NVidia GT 220. Fairly old model. Yes.

    The new card is an NVidia GT 630 (to be precise: Asus GT630-SL-2GD3-L.)

    When I tried to start X11, I saw an error (really quick) and the system did not come up. Looking closer into the matter, I could see that the NVidia ...

  • As I like to have Synergy working on my Windows boxes (i.e. laptops), I am saving a copy of the installer 64 bit version which works fine with WinXP and Win7. I'm about to test it with Win10 which is likely to accept it as is too. Just in case you did not know, Synergy is a driver that takes one mouse device and makes it work on multiple computers. In other words, you can use any number of computers with one mouse and one keyboard. Move the mouse to the right computer and you can use the keyboard on that computer. No need for a KVM anymore (Keyboard Video Mouse device that allowed you to ...

  • I have been wondering about setting up one of my computers for 2 or 3 users with 3 mice, 3 keyboards and 3 monitors.

    This apparently may require 3 video boards with Ubuntu. That could be a problem with AGP, but PCI Express may work fine with that. Only problem, in most cases boards only have 2 slots these days...

    Anyway, if I ever try to do that, I'll put the info here on how I got it to work... for now, you'll want to look at this page on Ubuntu:

  • I recalled reading somewhere that you could see the performance of NVidia cards under MS-Windows. Looking around I could not really see how that would be done. Today, though, I found out that perfmon does it all!

    To start perfmon, click on your Start button and enter perfmon and click Run. You may also start it from a command line although perfmon is a graphical tool.

    Once in there, click on ":Performance Monitor", it should appear under Monitoring Tools.

    That won't give you the GPU information though, not by default.

    When you right click on the area with the graph, you see ...
