This question already has an answer here:

I have graphics card Radeon HD 7730, I have intel i5 processor running Ubuntu 14.04 LTS. Output of fglrxinfo follows:

display: :0  screen: 0
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Mobile 
OpenGL version string: 3.0 Mesa 11.0.2

Output of lshw -c video gives me:

 *-display

This question has an answer lspci -nnk | grep -i vga -A3 | grep 'in use' for its output it gives:

Kernel driver in use: i915
Kernel driver in use: radeon

In my additional driver tab I see 3 drivers:

  1. Using X.ord Xserver -AMD? ATI dispaly driver wrapper from xserver-xorg-video-ati (open source, tested)

  2. Using Video driver from AMD graphics accelerators from fglrx-updates (proprietary)

  3. Using Video driver for AMD graphics accelerators from flgerx (proprietary)

The 3rd one is selected.

The response of lspci -k | grep -EA2 'VGA|Display' is

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
    Subsystem: Dell Device 0572
    Kernel driver in use: i915
--
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Chelsea LP [Radeon HD 7730M] (rev ff)
    Kernel driver in use: radeon
07:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 07)

Questions:

  • I want to understand if my AMD card is served as graphics driver or i915?
  • If not how can I make it happen?

    WARNING: output may be incomplete or inaccurate, you should run this program as super-user. – Did you try that? The definitive resource to determine the graphics adapter/driver in use is always /var/log/Xorg.0.log. – David Foerster Aug 6 '16 at 11:57

If you are using fglrx driver with dual graphics, you can check which adapter is in use In Catalyst Control Center, or by using a terminal command:

sudo aticonfig --pxl
  • It shows this message after this command aticonfig: No supported adapters detected – Vaibhav Dhoke Aug 4 '16 at 16:41
  • I want my graphics to be served from my graphics card Radeon HD 7730 . – Vaibhav Dhoke Aug 4 '16 at 18:19
  • Is Secure Boot disabled? Please edit your question and add output of lspci -k | grep -EA2 'VGA|Display' terminal command. – Pilot6 Aug 4 '16 at 20:04
  • can you please check now – Vaibhav Dhoke Aug 8 '16 at 14:47
