I want to know whether ubuntu comes with preinstalled graphic drivers like windows 8? or we have to manually download and install them. I just installed ubuntu 14.04 in my laptop. I installed steam and dota 2 but graphics are very bad. I have windows 8 also. in that it runs very fine - here is my driver information
lspci -vnn | grep VGA -A 12 01:00.0 VGA compatible controller : Advanced Micro Devices, Inc. [AMD/ATI] Thames [Radeon HD 7550M/7570M/7650M] [1002:6841] (prog-if 00 [VGA controller]) Subsystem: Sony Corporation Device [104d:90ac] Flags: bus master, fast devsel, latency 0, IRQ 47 Memory at b0000000 (64-bit, prefetchable) [size=256M] Memory at c4000000 (64-bit, non-prefetchable) [size=128K] I/O ports at 5000 [size=256] Expansion ROM at c4040000 [disabled] [size=128K] Capabilities: <access denied> Kernel driver in use: radeon 01:00.1 Audio device : Advanced Micro Devices, Inc.

My system information is showing like this for graphic card when u go into system settings and choose "details"
- memory 3.8gb
- processor intel® Core™ i5-3210M CPU @ 2.50GHz × 4
- graphcs Gallium 0.4 on AMD TURKS
- os type 64-bit = disk 110gb
Do I need to install AMD Radeon drivers into it or is it already installed? If it is already installed, then why does Dota 2 is running without using my graphic card, because textures, lightening and everything is real bad. O have been playng games for more than 5 years so I know about graphics, but I played them on windows till now. I m totally new to Ubuntu or Linux. please help what is wrong here? Or do i have to set any launch options for Dota 2 to run properly?
when going into system settings, software and updates, addtitional drivers it is showing the following:
-advanced micro devices, inc. [amd/ati]: thames[raedon 7550m/7570m/7650m] this device is using the recommended driver. --using x.org x server - amd/ati display driver wrapper fromxserver-sorg --using video driver for the amd graphcs accelerators from fglrx (propreitary) --using video driver for the amd graphcs accelerators from fglrx-updates
in the above three options 1st one is selected. what to do?
