how to tell my graphics board driver in linux? ## return from suspend laptop problem#

is it lspci -v | less? I tried that and nothing in there looks like a graphics board driver, but maybe I don't know what i"m looking at.

How can I tell which driver is running my graphics board? I need to get the answer so I can report back to someone helping me with a bigger issue in the debian-laptop newsgroup. If anyone here wants to jump on board and help with a solution to my bigger problem the post is copied and pasted below. But if not, The easier question is simply how to tell my graphics board driver. Thanks

(Ps. this is my first post here, and I read the two threads that you're supposed to read as a newbie, so I hope I followed all the rules) Thank you.

>>> newgroup posting of main issue I'm trying to resolve follows:

The graphics board driver, that is.

Could you please indicate me what's the driver that you're using?

I have looked for a solution in forum search, google, and other misc. Debian help pages. I've found many comments, but no solution.

The Problem: After suspending successfully (apparently, evidenced by blinking amber light) and resuming, the screen remains off. No backlight... blank screen.

Attempts at solution:
1. without the screen on and after resume I ctrl-alt F1, CTL-ALT 7, CTR-ALT 'whatever' and no effect on screen.
2. after resume with no screen, CTRL-ALT 1, login as root, type halt. computer shuts down.
3. after resume with no screen, CTRL-ALT 1, login as root, restart gdm, no effect.
4. after resume with no screen, CTRL-ALT 1, ALT-F7, no effect.
5. " " " " " """"""""""""""""""""""", Funtion key - F6 and F7 to adjust brightness, no effect

Is there a way at the command prompt to kill the screen and start it up again? I'm pretty much out of ideas.

Environment: Running Lenny with Linux Kernel 2.62 AMD64 (I dual boot w/ vista). Toshib A215-s4757, ATI Radeon graphics.

Thank you in advance for any help or direction.

Look at the log file at /var/log/Xorg.0.log

You should be able to weed it out quickly with
cat /var/log/Xorg.0.log | grep -i driver
Also, you can see loaded modules with
And you should be able to isolate your video card in lspci as so
lspci | grep -i vga
