Ubuntu 12.04 LTS , Dell d410 output to External Monitor/TV with docking
- by Gck
I am not able to see the video output on My external monitor/TV after installing 12.04 LTS. I had the same issue with 11 versions also.
This issue does not happen on 10.04 LTS version.
This is my setup.
Dell latitude D410 with Intel Mobile 915 GM/910GML express controller
using the Dell docking station
Connecting to my 42inch TV with DVI (from Docking) to HDMI cable (on TV)
If i close the lid, some times i am able to see the video output on TV, but the resolution is making the fonts so small, i cannot even see it and when i click displays option to change the resolution, the output goes off completely and it is shown now on the laptop screen.
one time, i got the output on both the screens, but i am not able to replicate that scenario even after trying the Fn+F8 key option on my laptop.
earlier some time back when i ran version 11.x ubuntu, i was able to get the output on both the screens (basically mirrored output) with large font resolution on my TV using the monitor Test tool as mentioned here :http://www.bigfatostrich.com/2011/05/solved-ubuntu-11-04-broken-external-display/
The problem with this approach is that i have to do it every time i restart the machine and more over the video output is present on both the screens (mirrored), which is of no use.
As i stated before, this does not happen with 10.04 LTS. With 10.04 LTS my laptop screen is off automatically and the output is seen on TV/external display.
Can anyone share any options that i can try?
How can we achieve the behavior of 10.04 LTS with respect to the External display on 12.04 LTS .
Thankyou very much for your help in advance.
