Firefox 4 about:memory

You blame Firefox 4 to be a memory hog? Check it out first by typing about:memory in the address bar. You'll get a nice detailed report of your browsers memory usage. While it's not guaranteed you'll understand every statistic available in the report, you can at least peek at the overall memory use, and see how much it's fragmented by comparing "memory mapped" and "memory in use" numbers.

Key sequence to kill the X server (Control + Alt + Backspace)

Current default for X servers as shipped in various distributions is to not enable the traditional Ctrl-Alt-Backspace key combination to kill the X server. If you would like to re-enable this feature, you may do so in your desktop's Keyboard Preferences application. You may also enable it for the current session using the command "setxkbmap -option terminate:ctrl_alt_bksp".


How S.M.A.R.T. are your disks?

GSmartControl is a graphical user interface for smartctl (from Smartmontools package), which is a tool for querying and controlling S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) data on modern hard disk drives. It allows you to inspect the drive's S.M.A.R.T. data to determine its health, as well as run various tests on it.

Running Nvidia display drivers with X.Org 7.3

Nvidia Linux driver 1.0-9639, 1.0-7185 and Linux kernel 2.6.23

Referencing the post Nvidia Linux driver 100.14.11 and Linux kernel 2.6.23. Here I have attached the patches for the older versions of Nvidia drivers. The procedure to follow is the same as described in the above document.

GNOME Desktop project 10 years old!

[img_assist|nid=1030|title=|desc=|link=none|align=left|width=100|height=114]Exactly 10 years ago, on 15th August 1997, Miguel de Icaza started his first announcement about GNOME Desktop project with this words:

We want to develop a free and complete set of user friendly applications and desktop tools, similar to CDE and KDE but based entirely on free software:

Nvidia Linux driver 100.14.11 and Linux kernel 2.6.23

Well, they're not working together. Unless you're not willing to tweak it a little bit. So, out of the box, you won't be able to test brand new Linux CFS scheduler, merged in the 2.6.23-rc1 release, if you drive your Nvidia card with the proprietary driver. I guess that's what we get for running binary drivers.

Your ATI Radeon very slow on Xorg X server 1.3?

This one has bothered me for a long time. The solution is, of course, simple. But, I still don't understand why was it necessary to force users to search so hard for this piece of information, where all the older X server releases worked OK out of the box?

If you find that after upgrading to X.Org 7.3 your display becomes very slow, and you own ATI Radeon, all you need to do is to put this line in the Device section of your xorg.conf:

Option "MigrationHeuristic" "greedy"

How to cleanup your GNOME registry?

[img_assist|nid=1030|title=|desc=|link=none|align=left|width=100|height=114]The other day I stumbled upon this neat tool that helps cleanup your GConf registry, called GConf Cleaner. While GNOME registry size isn't nowhere near the size of Windows registry, and thus shouldn't slow your computer too much, it's still nice to have a tool that cleans unused and obsolete entries.

The flash plugin and X.Org 7.0 (X11R7) font problems

If you are lucky to have fresh X11R7 on your desktop with all its new features and nice filesystem layout you might have noticed that some things have compatibility problems with it. Namely, if you have flash plugin installed you might not see text in flash content displayed properly, depending on how your Linux distribution handled the upgrade.
