I am using Fedora for some time now, but used Windows most of the time on my older Sony (VPCEA3C5E) laptop. The biggest reason is the overheating problem. The laptop gets hot and the fans spin at full speed. 80 degree Celsius or higher is not uncommon when starting a GlassFish server or do something else which require a little more from the laptop. On IDLE it hardly gets below 60 degree Celcius. I noticed there could be a problem switching the graphic cards as my laptop has an Intel and AMD/ATI GPU:

Mobility Radeon HD5650 and Intel Core i5-460M with Intel Graphics

After a lot of searching there were a few web pages which showed how to disable the AMD and only run on the Intel GPU which is good enough for me. The laptop itself has a 1600x900 resolution and an attached display is 1366x768 or 1920x1080 at most. But the laptop won't be used for gaming or other programs which require a lot of graphic force. Many of those pages require the file /sys/kernel/debug/vgaswitcheroo/switch on the system. Unfortunately there is no such file. After another Google round they stated there should be two VGA compatible controllers in lspci. But there is only the AMD controller after searching with:

lspci | grep -i vga

At the moment I run Fedora 20 Beta, but the problem is also with Fedora 19 and 18.

Here's some stuff to check. Firstly, disabling the ATI graphics may have been successful, but is there a setting in the BIOS that controls the Intel video chipset too. Perhaps that needs enabling/memory allocating. Secondly that lspci call, it is possible that the Intel video card doesn't report 'vga' - try lspci on its own and scan down the list yourself.

Thanks for the quick reply. I couldn't disable the ATI Graphics since there is no file to disable it and that file isn't creatable even when logged in as root. I already checked the BIOS settings, but unfortunately there are not so many settings available and none for the graphics. There are quite some Intel results after running "lspci". All the available are categorized by: Host bridge, PCI bridge, Communication controller, USB controller, Audio device, ISA bridge, SATA controller, SMBus and Signal processing controller. I actually wouldn't know which one of those could be the GPU...

None of those items are a video card. I cannot access specifications for that laptop from where I'm based (Sony think it's really clever to limit my access to info about products I can buy in the territory my IP address appears to be from) but I did find the specs posted on another forum. That laptop appears to only have a Radeon Mobility video chipset. There is no Intel video - the Core i5-460M is a mobile CPU, but the "with Intel graphics" bit you posted above may well be a typo, or a mistake on someone's part.

Thanks, but that is quite odd. Windows sees two graphic adapters in the device manager. That together with what is told on on the ARK Intel website (can't post a link yet) I really expect there should be an Intel Graphic card. The reason you might not see the device specifications is that this laptop is customized. Normally this laptop only has a 1366x768 resolution and most of them don't have an Intel Core i5 (or even an Intel Core i7), but Intel Core i3 which didn't fit my needs.

The specs were posted here, and that seems to reflect the system you have... it certainly has an i5 cpu. That is a forum site, though, so I'd expect a degree of inaccuracy. There is a manual for it here which might be useful, but doesn't really say much about the video chipset.
