Ubuntu – Switchable Graphics: Embeded graphics card problems

12.0464-bitatihybrid-graphics

I have a Dell Inspirion 17R 5721 It has a AMD graphics card and a Intel. I installed the drivers that AMD develops and I ran into the following problems.

Every time it's me that has to change the card from Intel To AMD and vice versa.

When I'm using Intel… Graphics don't actually work. The error I'm getting from a game when I run it is this:

ERROR: ld.so: object '/home/deus/Programs/Phoenix_Firestorm-Release_i686_4.4.2.34167/lib/libcrypto.so.1.0.0' from LD_PRELOAD cannot be preloaded: ignored.
ERROR: ld.so: object '/home/deus/Programs/Phoenix_Firestorm-Release_i686_4.4.2.34167/lib/libssl.so.1.0.0' from LD_PRELOAD cannot be preloaded: ignored.

ERROR: ld.so: object '/home/deus/Programs/Phoenix_Firestorm-Release_i686_4.4.2.34167/lib/libcrypto.so.1.0.0' from LD_PRELOAD cannot be preloaded: ignored.
ERROR: ld.so: object '/home/deus/Programs/Phoenix_Firestorm-Release_i686_4.4.2.34167/lib/libssl.so.1.0.0' from LD_PRELOAD cannot be preloaded: ignored.

What I understand from this is that some libraries couldn't be loaded?
But why does it work when I'm using AMD's card and not when I use Intels?

Before AMD put out drivers for my graphics card in linux, I used Intel graphics card and it worked.

Since Discrete graphics are not well supported (talking about crazy fan speed and heat problems) I want to use only Intel's graphic card and keep discrete deactivated.

Any ideas on how to make Intel run my game again and keep discrete card from running (freaking fan drivers me crazy) when I use linux?

If you want to disable the AMD card, follow this link

Also you may want to uninstall the proprietary drivers :sudo apt-get remove fglrx*

Ubuntu – How to re-configure graphics from Intel integrated to Intel / ATI switchable

I found a solution for while googling. You have to put a script in rc.local specifying which VGA you want to use.

This link explains everything.

I will post important notes here:

First install needed driver and script from git

sudo apt-get install git && cd ~/  
git clone https://github.com/mkottman/acpi_call.git  
cd acpi_call && make  
sudo insmod acpi_call.ko  
chmod a+x test_off.sh

de-activate ATI VGA
```
sh test_off.sh
```
Now you can check if your ATI VGA is already disabled by lspci -vnnn | grep VGA.
It will show the following output:

00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09) (prog-if 00 [VGA controller]) 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc NI Seymour [AMD Radeon HD 3650M] [1002:6760] (rev ff) (prog-if ff)

If it works, to make this run at boot, edit /etc/rc.local:

sudo insmod /acpi_call/acpi_call.ko
sudo sh /acpi_call/test_off.sh

Also, remove radeon blacklisting by editing /etc/modprobe.d/blacklist.conf:

#blacklist radeon

You should have xorg.conf like this to make VGA detectable :

 Section "ServerLayout"
 Identifier "aticonfig Layout"
 Screen 0 "aticonfig-Screen[0]-0" 0 0
 EndSection

 Section "Module"
 Load "glx"
 EndSection

 Section "Monitor"
 Identifier "aticonfig-Monitor[0]-0"
 Option "VendorName" "ATI Proprietary Driver"
 Option "ModelName" "Generic Autodetecting Monitor"
 Option "DPMS" "true"
 EndSection

 Section "Device"
 Identifier "aticonfig-Device[0]-0"
 # Driver "fglrx"
 BusID "PCI:1:0:0"
 EndSection

 # Section "Screen"
 # Identifier "Default Screen"
 # DefaultDepth 24
 # EndSection

 Section "Screen"
 Identifier "aticonfig-Screen[0]-0"
 Device "aticonfig-Device[0]-0"
 Monitor "aticonfig-Monitor[0]-0"
 DefaultDepth 24
 SubSection "Display"
 Viewport 0 0
 Depth 24
 EndSubSection
 EndSection

Note: To activate ATI/AMD radeon VGA again: Just comment what we've added to rc.local

Solution 2

I found this solution from askubuntu.com, I might be easier to put into practice:

This question assumes using vga_switcheroo.

Add this to /etc/fstab:

none  /sys/kernel/debug debugfs defaults 0 0
