[Bug 312756] Re: support graphics card hot switch

 

In answer on the email request to post information about my graphic card and model of the system.
Here is my gathering technical information to improve Linux support on hybrid graphics card.

See attached DSDT.dsl file.

root@HOST:/tmp# dmidecode -s system-product-name
M51Vr               
root@HOST:/tmp# lspci | grep VGA
01:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3400 Series


NOTE:
while generating the acpidump.txt file I got the following message:

root@HOST:/tmp# acpidump > acpidump.txt
Wrong checksum for ATKG
Wrong checksum for ATKG!

Here are the last lines from the command acidump to standard output:
