Hello:
I installed 64 bit Karmic on my Inspiron 15n laptop today and neither my display or my wireless card works. I have an intel integrated graphics card and a broadcom bc4312 wireless card - more details below
1) Display issues
My display did not work during the installation so I had to install using an alternate cd. When the computer boots, it displays "grub loading" for 1 second, then a blinking cursor for about 5 seconds, then nothing. After a minute or so, I hear the ubuntu login sound, so I know that X has started. Hitting Ctrl+Alt+F1 doesn't take me to a console, just the same black display. I tried plugging in an external monitor, and everything seems to work on that. I can see the splash screen before X starts, then the prompt to login. Using the external monitor, I installed all of the Karmic updates with no improvement.
To reiterate, the problem occurs before X even starts. When the display goes blank, there is a weird screen distortion for a second, but that is all. I can't even get to a text console.
2) Wireless issues
The system->administration->hardware drivers dialog has the option to install the b43 wireless driver. I installed it, but my wireless still does not work. I googled around and saw that some suggested installing bcmwl-kernel-source package, which I think is the proprietary driver. This causes my computer to immediately crash. Restarting leads to an immediate kernel panic.
So these are my pretty serious usability issues. I think I will wait a day or so to see if anyone can help. Otherwise, I am going to upgrade to a clean Jaunty install. Everything works fine in Jaunty...
Thanks
