Bootloaders: Windows 7 and GRUB

My recently bought SSD is only 64GB, and i've been toying with all OS's i might like. Sometimes, a bootpartition gets damaged. Here's how to fix it.

Restoring the Windows 7 bootloader:
Since my computer contains only Windows 7 i no longer need GRUB. Its defect anyway since extending the Windows 7 partition, and i like a fast boot so i don't like the countdown menu.

How to:
  • Boot from Windows 7 DVD
  • Select language
  • Choose Repair
  • Choose Windows 7
  • Choose Command line
  • Type this in without the quotes ("): "bootrec /fixmbr" and press enter.
  • Type "bootrec /FixBoot" and press enter.
  • Restart
Ofcourse its also possible to just restore GRUB: check out Supergrubdisk.

Installing VLC 1.0 on Ubuntu 9.04 (Jaunty)

By default the jaunty repository maintained by Canonical doesn't include the latest VLC release. Bummer! Yet very easy to overcome.

UPDATE 20091010: Found a better method:

Never mind the rambling below.

To install VLC and other affected applications enable the "Third Party Software" repositories:
  • start Synaptec Package Manager, find it at System > Administration
  • open Repository Settings, via Settings > Repository
  • open the tab "Third-Party Software" and check the two default items;
http://archive.canonical.com/ubuntu jaunty partner
http://archive.canonical.com/ubuntu jaunty partner (Source Code)
  • Apply your settings, and choose Reload. Done!

You may now search for the latest version of your favorite non-Canonical-maintained application, and it should still show up.

Thats all folks, easy as pumpkin pie. And i don't even like pumpkin pie.

Multi/Dual monitor setup with Synergy

Today my workplace was below par: my dual monitor workstation was defect and i even forgot my Acer notebook. What should i do?

All i had to work with was this pile of retired rackservers that i tend to accumulate. These wheren't up to speed, so i decided to strap them together and make the most out of it. I wanted to use these as a more powerfull (multimonitor) workstation. So i installed the latest Ubuntu on two of them.

Then i remembered learning about Synergy years ago.
Synergy lets you easily share a single mouse and keyboard between multiple computers with different operating systems, each with its own display, without special hardware. It's intended for users with multiple computers on their desk since each system uses its own monitor(s). - Synergy sourceforge website

Hearing lots of people had trouble setting getting it to work, here is a short (Ubuntu) howto. 
  1. Install QuickSynergy on all systems
    Synaptec Packet Manager should work, otherwise try this method: Applications > Add/Remove, now choose "Show: All available applications", and search for QuickSynergy, check it in the list, and click Apply.
  2. Run QuickSynergy on host
    This is the workstation that has the mouse and keyboard connected. Pick the most powerfull machine.
    Enter the IP hostname of the client in the directional box of your choice. (Moving through this edge makes your mouse spawn on said computer.)
    Click the Execute button.
  3. Run QuickSynergy on client(s)
    Enter the IP address of the host in the Use tab.
    Click the Execute button.
  4. Done
    Move the mouse to the edge of the host screen - it should now appear on the client screen!
I still prefer Compiz on Ubuntu, but this is the next best thing. Especially if you can trow hardware at the problem. Now i MacGyvered myself a decent workplace.

Expect a howto on permanent Synergy setup, so you wont have to reconnect after each reboot. Oh and Synergy works across all mayor platforms. Its terrific! Check their site.

Also, i've given up on my workstations hardware problems. The AGP card used to work fine after kicking the machine once or twice... the last fourty didn't make a difference. Except for the satisfaction.

Update 20091005: Adjusted article; i discovered that entering the clients' hostname (instead of IP) on the host (see 2nd step) is more successful.
