How do I know if I am using Matrox's Linux driver for G400?

How do I know if I am using Matrox's G400 driver in Linux? I am not sure if I am using the stock one from Red Hat (7.1) or the one I downloaded.

Thank you in advance.

For one thing, Matrox's PowerDesk utility won't work with the the standard (XFree86) driver. You need Matrox's drivers (mga_drv.o and mga_hal_drv.o) for the utility to talk to the hardware.

[Ees]

grep mga_hal /var/log/XFree86.0.log

(or wherever your X log is kept)
This will display some lines if you're using the Matrox driver.

Alternatively:

grep -q mga_hal /var/log/XFree86.0.log && echo "mga" || echo "stock"

Thanks Martin. Argh!

[ant@ANTux-P2 ant]$ grep mga_hal /var/log/XFree86.0.log
" nt@ANTux-P2 ant]$ grep -q mga_hal /var/log/XFree86.0.log && echo "mga" || echo "stock
stock

Is it me or does rerunning XConfigurator command not a good idea? I had to rerun it because I replaced my broken monitor. How do I reuse the Matrox's Linux driver without a reinstall or do I need to do a reinstall?

Thank you in advance.

Right, the problem is that I had to replace my broken monitor. I reran Xconfigurator to tell Linux about the new monitor. I am not sure if Xconfigurator reverts back to XFree86's driver instead of Matrox.

I hope redownloading and rerunning install.sh puts my drivers to Matrox. Do I need to edit anything for XF86Config-4 file?
