[SOLVED]Attempting to Fix Screen Tearing

I have been attempting to remove screen tearing that occurs as a result of Xorg. From doing a bit of research, I can apparently add a config file to /etc/X11/xorg.conf.d/, called 20-intel-gpu.conf. In that file, I have the following:

 Section "Device"
        Identifier "intel graphics"
        Driver "i915"
        Option "Tearfree" "true"
EndSection

However when I try to restart xorg with "startx", it gives me an error saying that it was not able to find the module. The logs in ~/.local/share/xorg/Xorg.0.log say this:

[   231.132] (II) LoadModule: "i915"
[   231.132] (WW) Warning, couldn't open module i915
[   231.132] (EE) Failed to load module "i915" (module does not exist, 0)
[   231.132] (EE) No drivers available.
[   231.132] (EE)
Fatal server error:
[   231.132] (EE) no screens found(EE)
[   231.132] (EE)

I initially tried specifiying the

 Driver 

option in the config file as just "intel", but that resulted in the same error. Removing this config file makes xorg run normally, so it clearly does not like this config file. I ended up trying "i915" because that's what this command gave:

$ lspci -k | grep -A3 -i vga
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
        Subsystem: Lenovo ThinkPad T420
        Kernel driver in use: i915
        Kernel modules: i915

Is there anything else I can put for the driver option, or another method to fix screen tearing, or am I just stuck with screen tearing?

Have you installed the Intel Driver ?

Output of:

lsmod | grep i915

Re: [SOLVED]Attempting to Fix Screen Tearing

I ended up trying "i915" because that's

…"wrong".

Have you installed the Intel Driver ?

Re: [SOLVED]Attempting to Fix Screen Tearing

Installing the xf86-video-intel package, and replacing the Device name with intel seemed to do the trick. No screen tearing now.
