Contacts, Calandar back up on online server

For a while now I have been looking for a way to sync my contacts, on my laptop and cell phone as well as my calendar. Scheduleworld.com provides a free way to do that.

It is compatible with Google's gmail, and gcal. So it provides an all in one solution. It also works with evolution mail client in Linux with a special plugin you can download.

All the information is on their web site. Check out these links to find out more.

nvidia restricted binary drivers and settings

I have found a really nice tool for setting up the xorg.conf and daul view. From the command line in Ubuntu type gksudo nvidia-settings. Up pops nvidias GUI tool for setting up your nvidia card and xorg.config.

Only it has problems, or at least I had problems. they relate to where some of the advanced nvidia settings are stored in a file called .nvidia-settings-rc. From your home directory type ls -a .nvidia-settings-rc. This file is basically used to initialize your graphics card at boot and is linked into the boot process through the init folder in /etc/rcX.d.

The problem I had with this file was that the permissions on it doesn't allow the program to rw access it and execute it. I may be wrong here. What I did to fix the problem was change the permissions from
user@user-machine:~$ ls -l .nvidia-settings-rc
-rw-r--r-- 1 user user 1511 2007-06-06 18:33 .nvidia-settings-rc
user@user-machine:~$ ls -l .nvidia-settings-rc
-rwxr-xr-x 1 aaron aaron 1511 2007-06-06 18:33 .nvidia-settings-rc
with a chmod 755 .nvidia-settings-rc. now it probably dose not need the execute permissions some thing to experiment with but make sure it has the rw.
basically try:
$ chmod u=rw,g=rw,o=rw .nvidia-settings-rc
$ gksudo nvidia-settings.

I still get a lot of ERROR .... (no Display connection) messages on the command line but at least now it actually generates the xorg.conf file in the /etc/X11/ directory.

I'm not sure what the error messages mean or how to fix it. It has some thing to do with the advanced options of gamma, colour saturation. This can be fixed but I didn't find it necessary to. There is some discussion at the nvidia forums. Check out this thread http://www.nvnews.net/vbulletin/showthread.php?t=61396 it seams to have the most though discussion on fixing it.

Please post you comment on this if you have any solutions for the ERROR ... (no Display connection) problem.

Ubuntu 7.04 Feisty Fawn

I am a real distro whore and have moved to yet another one. My favorite so far Ubuntu has always been on the top of the list of distros I wanted but with telkoms internet connection prices I have always chosen distros with more software then comes on the Ubuntu free cd.

I have used fedora 4, 5, and 6. I think that fedora gets a lot of free publicity because of Red Hat. It is no way near to the functionality and ease of use in the GUI that can be found in either suse or Ubuntu. I think any one who uses fedora just cause of it's relation to Red Hat should consider moving to suse or Ubuntu. I have only used these distros for desktop productivity, programing and web development. So as far as running a server is concerned I can't cant say which one is better.

I have used suse 9.2, 10, 10.1 and finally moved over to a complete Linux system one my acer travelmate 5623 with 10.2. I have to say that suse with yast make Life very easy. The GUI based install can be done buy any one and it is rpm based so all the red hat packages tend to be compatible. I have found it to be a little slow, and it has crashed on me relating to X windows problems. I have used the 3D desktop across two screens on suse with out much problems, although I prefer to use it with out desktop effects as it works better because Lap top and 19" dont have the same resolutions. Over all I am very happy with novels suse product. In terms of usability I have to say it is one of the easiest I have used.

I have installed Debian on an old Pentium 1 I had lying around. It was a pain, never got X to work so I never used the Gui. It was a pain to install, but then they aren't aim at making it easy to use they are aiming at making it stable so if X cant figure out what settings it is meant to have then it is doing what it was created to do be stable.

Now I have moved completely to Ubuntu. I was able to get a friend to download the dvd of 7.04 and this has so far been what I am looking for. I have struggled with X. Similar problems to that of Debian, the auto config is that automatic and requires some expert knowledge on how to set it up. But in general after googleing a bit I found the solutions I needed. For X and some other commonly tried advanced configurations such as visualization go to librenix. I also found that nvidia has made a graphical tool called nvidia-settings to solve most problems I will put my solution in a new post to make it easy to Google.

Ubuntu is faster then suse probably cause their generic kernel is using more i686 code and take better advantage of my SMP (symmetric muilt-processors, dual core). I have been playing with beryl and it is definitely hands down the best desktop effects product out there. More settings better features every thing is better. I still need to do some development on Ubuntu to get a better feel for it but so far it is exactly what I am looking for a LAMP system.

I understand them not including Java, adobe, and some other free but proprietary licensed software but once every thing is up and running all you need to do is enable the relevant repos through synaptic and you can easily download them. Synaptic comes close to yasts in that it allows you to add cd and dvd repos which make life a breeze. Synaptic though is not an all in one control panel like tool which is what yast is. I will stick with the way Ubuntu is laid out for the moment, though I might try to install yast a little later.

xorg and xserver issues in Linux ubuntu

Dual monitor support in Linux seam lacking, so do tools to configure them. May be I not looking hard enough. I would have expected xorg to have written some nice GUI tools to configure the product.

Having to edit the xorg.config text file seams like a real waste of time, and is very confusing for new linux users. Do a search on google for xorg prolems and xserver problems there are just to many. Most come down the the automatic detection program / scripts not working. I dont have a problem with this cause there is just so much hard ware out their.

My suggestion for the the guys at xorg or who ever to create a nice gui front end for the xorg.config file with human understandable instructions on how to create a working conifg file. I will have a look into this my self when I have time. but in the mean time as I have now moved to ubuntu 7.04.

This link will suffice to help those wanting to create set up thier monitors for a dual view system http://ubuntuforums.org/showthread.php?t=221174.
This one is for just after install isues https://help.ubuntu.com/community/FixVideoResolutionHowto.
Like if you get the famous xserver failed to start error after a new install or you have screen resolution problems.

Free online and downloadable books

I am going to start of list of links for finding good free books to view on line or to down load. I will have a similar list as I have on the right hand side for ftp sites.

Good list of linux and open source materails as well as others. http://eo.yifan.net/users/k/aravind/olbooks.htm
