[gentoo-user] environmental variables ?

[Dave S]

I throw myself on your mercy, this is for a kubuntu install not a gentoo 
install - but you guys are the most technical bunch I know :)

I start an app with 'gksudo simple-backup-config', (a gtk backup 
utility 'sbackup') and all is well, the GUI it is rendered perfectly.

I upgrade my system.

I start the app with 'gksudo simple-backup-config', YUK it looks like someone 
chewed it, the graphics are so primitive, white blocks around the GUI radio 
buttons, the tabs are separated and look like loose teeth, the buttons have 
lost their border and are just icons.

Experimenting I found that 'gksudo -k simple-backup-config' restored it to its 
former beauty, as did straight 'sudo simple-backup-config'.

Ahh I thought - environmental variables so I dug out a script to dump all 
environmental variables, did a diff between gksudo and gksudo -k and got ...

< DESKTOP_STARTUP_ID = gksudo/|home|vanda|
test/27282-0-vanda-comp_TIME771509819
---
> DESKTOP_STARTUP_ID = gksudo/|home|vanda|
test/27292-0-vanda-comp_TIME771642528
13c13
< HOME = /root
---
> HOME = /home/vanda
38c38
< XAUTHORITY = /tmp/libgksu1.2-AbpNh8/.Xauthority
---
> XAUTHORITY = /tmp/libgksu1.2-wNoSTR/.Xauthority

Not much change there. OK I am stumped. what else changes between gksudo and 
gksudo -k to affect GUI rendering ?  I know its no big deal but I would like 
to know. :)

Thanks in advance

Dave
