ATI Radeon HD Drivers Woes

Guys I am still learning Linux. I moved from Windows years back. Recently since Ubuntu 14 I am having issues with my Laptop. The graphics is an issue I believe. Its Radeon HD 7000 on a VAIO with broken screen. So its hooked to a 42" Plasma. I think Its got decent configuration for OBS. However I get very low frame rate first of all and its almost 100% CPU all the time while streaming. At idle its more than 70% for all cores. Its eating the CPU like hell. The Fan is behaving like a jet fan as soon as I open OBS. At present the OBS is just running idle. No streaming no Recording. But still I can feel the heat dissipated from the fan vent.

I am not good at Linux, I am still fiddling with it, Please help me. I may possibly need help with my Linux setup as well. Thanks in advance.

I have a hunch that its either my bad hardware or ill configured Linux /video drivers. Most probably Drivers and then may be hardware. I heard that my laptop has hybrid graphics. I would like to determine that with your help. I am not sure though. I have not been able to get into bios since i removed the factory/recovery partition running viao care in UEFI. If anyone could help me with a perfect setup possibly with Linux I would be grateful.

Thanks In advance. Please help me sort it out. I have tried all Ubuntu 12 14 17 and 18 as well …

Right now I am back on running ubuntu 14.04.5 …

Someone from OBS forum told me I am running the machine in Virtual Mode which I am sure I am not. But the log says that. I will be extremely thankful for the community if I can get help to solve this problem. And may be understand the problem in the first place so that I can learn more about Linux.

Here is my OBS log
