Hi, all, I got a HP env 5306tx laptop with dual GPUs, and I faild to install driver for it. I have tried official driver, rpmfusion, bumblebee, all failed. My dist is fc18-i386, with security boot disabled and legacy boot enabled. What is bothering me is that nvidia driver leave the screen blackout. When I reboot, I can dimly recognize a fedora logo in the center of screen, which is nearly blackout. So I cannot enter the system, and nothing changes after I add 3 at the end of grub command(and remove all these kernel options) or press ctrl-alt-fn. My questions is: * Why nvidia driver affects run level 3 and TTY? * How to enter system and remove installed drivers? Another non-related question is TTY is not working properly before I install nvidia driver. If I boot in runlevel3, and I enter TTY2 before login, the screen will flash between tty1 and tty2, or stick in tty2(cannot switch to other TTYs). I don't know it is a hardware problem or software problem. Any advice will be appreciated. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
