How to select a display adapter from a laptop which has dual graphic card's

English Hardware
#1

Hi recently I have bought Toshiba satellite laptop it’s model number is C55-b894 and installed opensuse 13.1 on it.

It has dual graphics card’s due to which I think X Windows System is not functioning properly.

I have found in the laptop manual the following information related to graphics.
AMD Radeon™ R5 M230. memory amount : 1GB dedicated VRAM. memory type : DDR3 Video RAM

So I have installed amd catalyst software

I am providing the output of the two commands related to display configuration below

linux-lnx2:~ # glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: AMD Radeon R5 M230 Series
GL_NV_conditional_render, GL_NV_copy_depth_to_color, GL_NV_copy_image,
GL_NV_conditional_render, GL_NV_copy_depth_to_color, GL_NV_copy_image

linux-lnx2:~ # /sbin/lspci | egrep “VGA|3D”
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)
linux-lnx2:~ #

I want to use amd display adapter as default and ignore Intel’s so I have went to BIOS configuration but I can’t found any menu related to graphics card’s configuration.

Can you suggest how to disable display Intel graphics card either in BIOS or OS level.

What makes you think that the proprietary driver and discrete AMD adapter are not working properly?

You might want to share /var/log/Xorg.0.log with us. It’s a lengthy file, so post it to http://paste.opensuse.org/ and paste the link to the uploaded file here

I don’t know much about hybrid graphics, but I’ve read that recent Catalyst drivers can cope with switching between discrete and integrated graphics adapters using the ‘aticonfig’ utility.

This Ubuntu-based guide might be helpful (it will depend on having the right Catalyst drivers installed though)

For example, reporting the default adapter

aticonfig --lsa

Setting the discrete adapter

sudo aticonfig --px-dgpu

and enabling the integrated (Intel) adapter

sudo aticonfig --px-igpu
