[ubuntu] Things to do after installing Ubuntu Server 12.04

Calendar July 30, 2012 | Posted by admin
Hi guys,

I’m just wondering, is there really a "Things to do after installing Ubuntu Server 12.04"? or after the installation you can just do whatever you wanted to do or install whatever you wanted to install??

Thanks in advance…

[ubuntu] Wireless not working after upgrade to 12.04

Calendar May 5, 2012 | Posted by admin
Hi,

I recently upgraded to 12.04 and now the wireless connection keeps dropping after a few seconds.
None of my other devices have a problem with my router and vice versa so I can only think it’s this latest distribution that is causing the problem.

Here are some details.

Code:
Ethernet controller [0200]: Atheros Communications Inc. AR242x / AR542x Wireless Network Adapter (PCI-Express) [168c:001c] (rev 01)
        Subsystem: Askey Computer Corp. WLL3141 (Toshiba PA3613U-1MPC) 802.11bg Wireless Mini PCIe Card [144f:7128]
        Kernel driver in use: ath5k

And here is the output from my syslog.

Code:

[ubuntu] gnome-shell fails after nvidia driver update

Calendar December 7, 2011 | Posted by admin
I have been having this problem since I installed ubuntu 11.10 on my laptop. After installation everything was fine, I installed gnome 3 and restarted computer. It was working fine until I upgraded nvidia driver from 173 to the "recommended" via additional drivers and restated again. I have noticed gnome with effects fails but with no effects working fine. I re-format the computer and made fresh install again and installed gnome 3. It was working again until I upgraded the nvidia driver. I have tired to install nvidia before and than gnome 3 but this did not work either. Nothing(keyboard, mouse even on/off button) when I turn it on with gnome(with effects). If somebody has any idea how to solve this, please tell me. Unity is not what I really want to use.
