VMware server 2.0 blank screen issue

2010-10-05T19:27:00.000-07:00

I installed VMware server 2.0.2 on Ubuntu 10.04 and after a successful installation when I run it brings up a blank screen in the browser. I've tried several solutions given by the VMware community, but it worked only after activating ss2v2 on the browser. To enable sslv2 type about:config on your browser. Filter for security.enable_ssl2. Activate it by double clicking it.

Taprobane GNU/Linux

2005-09-15T23:28:00.000-07:00

I installed Taprobane GNU/Linux 0.4.1 today. I doesn't contain a installer. So I had to do install it manually. But I think the manual installation is much easier than a installer ;-) These are the installations for manual installation by Anuradha Ratnaweera which I got from Taprobane mailing list.

- [optional] run qtparted and create a Linux partition and a swap
partition(s) if you don't have them. (Let's assume that you use
/dev/hda2 as the linux partition and /dev/hda3 as swap).

- Format the partitions
mkfs.reiserfs /dev/hda2
mkswap -v1 /dev/hda3

- Mount the partitions
mkdir /mnt/taprobane
mount /dev/hda2 /mnt/taprobane

(mount additional partitions if you want to, e.g.: an additional
/home partition.

- Copy everything in /gnu-linux/ to /mnt/taprobane/.

cd /gnu-linux/
cp -a * /mnt/taprobane/

- Edit /mnt/taprobane/etc/fstab and add the partition details

- Edit /mnt/taprobane/boot/grub/menu.lst

- Copy /mnt/taprobane/boot/grub/menu.lst to /boot/grub/

- Run grub and install the bootloader

grub
> root (hd0,1)
> setup (hd0)
> quit

- Edit /mnt/taprobane/etc/{passwd,shadow,group,gshadow} and change
"taprobane" to the username you like to use.

- Edit /etc/kde3/kdm/kdmrc and chnage these lines as necessary:

AutoLoginEnable=true
AutoLoginUser=taprobane

There is a bug in 0.4.0 which makes the xorg.conf file from being
created for the second time in an install. 0.4.1 should work without
a problem.

However, in 0.4.1, we remove /var/log/{syslog,messages,kern.log} in
order to avoid a large amount of log messages from being generated.
This is not necessary for hd installs. Removing /etc/init.d/rmlogs.sh
and link from /etc/rc2.d/S99rmlogs.sh should fix this.
