I installed Ubuntu 15.04 on my Dell Inspiron with ATI Radeon HD 7730M graphics card. I was under the impression that Ubuntu will use my graphics card as default graphics device but it does not seem so.
In Details section of System setting I see the following:
Graphics: Intel® Ivybridge Mobile
But in additional drivers I see this as enabled and recommended:
Using X.Org X Server - AMD/ATI display driver wrapper from xserver-xorg-video-ati(open source, tested)
Output of lshw is as follows:
dataslayer@ds-Inspiron-7520:~$sudo lshw -c video *-display description: VGA compatible controller product: 3rd Gen Core processor Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:31 memory:c1000000-c13fffff memory:b0000000-bfffffff ioport:4000(size=64)
This says that driver is i915 which I suppose are Intel drivers.
I need some help in setting up my system to use ATI graphics card instead of Intel's graphics.
I have not installed fglrx yet and do not intend to do so unless absolutely necessary.
Thanks for any kind of help.
