how do I check if linux can see and use my discrete graphics card?
@lizardsquid you'd have to check on the driver utility
catalyst for ATI, nvidia setting for idem
@Efi I have an ATI card, but I have no idea how to access catalyst
@lizardsquid you should have a shortcut if it's installed properly
did you install the proprietary drivers for it?
@Efi m-maybe?
I don't know how to do that
@Efi also I don't have a desktop environment, so no shortcuts
@lizardsquid in xfce4 a shorcut goes in the settings submenu *shrug*
on linux you have to select the non-free repo tag to get the drivers, on windows you install them with an installer from the ati web
@lizardsquid see: lspci | grep -i "VGA"
check if driver loaded:
dmesg | grep "nvidia" # or radeon, fglrx, nouveau, bla
if can use: some GL-demo, which displays the default graphics card?
@snaums lspci doesn't exist on my system for some reason, but dmesg shows positive results for both radeon and amdgpu
when I run stuff in wine, it can only detect my integrated card
@lizardsquid
Your ATI card is likely supported on Linux through MESA, but I'm not sure how it'll work on your frankendistro... I have zero experience with sabayon or gentoo...
@snaums
@lizardsquid Make a live usb?
@gemlog I'm not sure how that helps?
@gemlog I'm already running linux
@lizardsquid Oh! That's an important bit of information :-) I thought you were contemplating running linux.
and check performance:

@gemlog ok so I've found the problem: everything's installed correctly, but Xorg is using the integrated graphics drviers. How do I set it to use the amd ones instead?
@lizardsquid Depending on your linux distro, you may be able to find a 'driver manager' in your main menu.
Otherwise, the old-school way is to edit a file in /etc. I haven't had to do that for yonks though.
@gemlog I don't have any kind of menus, I'm running a bare window manager with no desktop environment
I'll see if I can find something, though
@lizardsquid There's no rule against having e.g. 5 different DE's installed at once. If you are resource-constrained, you could run one temporarily just to use the easy gui :-)
Anyhow, I'm sure you are on the right track. Bon chance! I have to go to work now.
follow up question: how can I check that wine is using that card, instead of the integrated chip?
