Hello everybody,
Well ... I want to install backtrack 5 r3 64bit on my laptop, HP Pavillion DV7-4090ef. the first problem I got is having a black screen after typing startx during the installation, but it was solved with typing the tub button and adding these words xforcevesa noapic noapic irqpoll--, after that I got into the graphic mode and I installed it well.
But the display card is not installed, whenever I install the driver I get whether "the black screen" after typing startx or the "fatal server error: no screens found" error.
and it has the ATI Mobility Radeon HD 5650 Graphics (switchable) Video Graphics.
I tried these steps and almost every solution I found on the internet, but without any satisfied result.
Is there any real solution that I can apply to get rid of this problem ?
please if any solution is suggested, it should be accompanied with its undoing command because I don't want to install backtrack from scratch again.
Thank you in advance.
