AMD Radeon HD6470M

[brainbox]

Hey,

It looks like there maybe an issue with AMD Radeon HD6470M chipset, as soon as xorg loads at boot, screen goes completely black, unable to kill xorg using backspace key.. it could be refresh rates...

hi,

have you tried to boot with other drivers?

on Bootscreen Press E and remove the ,,vga=123" replace it with radeon or vesa press CTRL + X when your done.
the radeon Drivers worked for me (HD6310).

try 'Backtrack Stealth' mode

[cheebu]

could you give me a little bit more detail...
The button to change the line is Tab not E

the line goes like this:

/casper/vmlinuz file=/cdrom/preseed/custom.seed boot=casper initrd=casper/initrd.gz text splash vga=791--

thats the line for the BackTrack Text - Default Boot Text Mode

i have a SONY VAIO C Series thus the Radeo HD 6470M

I'm having the same exact problem. I haven't tried editing the boot commands, though. Installing/Reinstalling the drivers didn't work. I'll let you know.

@brainbox and @psylence,

Hope this may help.

Here's another super sweet thread on the issue: http://www.linuxquestions.org/questi...nstall-893973/

All:

Problem (somewhat) solved!

Here's what I did:

#vi /etc/default/grub

Edit GRUB_CMDLINE_LINUX_DEFAULT to say:
GRUB_CMDLINE_LINUX_DEFAULT="text splash nomodeset i915.modeset=1 radeon.modeset=0"

Save & exit vi

#update-grub
#fix-splash

Install this: http://support.amd.com/us/gpudownloa...eon_linux.aspx

#fix-splash
#reboot

I say "(somewhat)" solved because the Catalyst Control Center still won't recognize my video card (prolly 'cause it's disabled in the boot code), but the resolution is now fixed at 1600x900. So, I'll take it!

Thanks for all the help.

I came up with this method that seems to work for me (radeon HD6310M) it will prolly work on the HD6470M aswell .


bOOT UP USING FLASHDRIVE OR LIVE CD

ON THE BOOT SCREEN PRESS THE "TAB" KEY ON THE "TEXT MODE" line

THEN CHANGE THE LINE:/casper/vmlinuz file=/cdrom/preseed/custom.seed boot=casper initrd=casper/initrd.gz text splash vga=791--

TO: /casper/vmlinuz file=/cdrom/preseed/custom.seed boot=casper initrd=casper/initrd.gz text splash nomodeset vga=791 radeon.modeset=0

PRESS ENTER

--------------------------------------------------------------------------------------------------------------------------------------------

WHEN U REACH root@bt

TYPE: vim /etc/default/grub

SCROLL DOWN TO THE LINE: GRUB_CMDLINE_LINUX_DEFAULT="text splash nomodeset vga=791"

PRESS THE "I" KEY

CHANGE : GRUB_CMDLINE_LINUX_DEFAULT="text splash nomodeset vga=791" TO: GRUB_CMDLINE_LINUX_DEFAULT="text splash nomodeset vga=791 radeon.modeset=0"

HIT "ESC" KEY

HOLD DOWN THE " SHIFT" KEY AND PRESS ":" KEY

THEN PRESS x KEY AND ENTER..........IT NOW SHOULD WRITE

TYPE: update-grub PRESS "ENTER"

(ignore the error after "update-grub" if u boot up off a live disk)

Type: startx

Thanks, yo. That's actually the exact solution that worked for me as well.

However, this essentially limits BackTrack to using the lower-quality integrated chip rather than the Radeon. Do you think there's any chance we could swap the options to enable the ATI card and disable the integrated one instead?
