Linux Problems:

Removed RHEL 6.4 and got Fedora 19(due to habitual use) setup with dual boot Windows 7.

Have been facing some touchpad issues. It some times does not recognize the touch! Cant' find dedicated drivers.

Got Nvidia video drivers installed. Screen looks good but cannot set to a lower resolution(1920x1080)! Screen overflows! i.e. I can only see about 25~30% of a fully maximized window rest overflows out of the screen. If anyone was able to set this up properly, please share your xorg.conf. I believe this is a panning issue. Am I right?

And have not been able to find network drivers for DELL 1550.
PCI ID : BCM4352

b43 and b43legacy says it's still not supported.

Broadcom BCM94352HMB with Chip 1: Broadcom BCM4352 says there is a driver available here Broadcom : Linux STA driver Although the readme says support for 4352(not BCM4352) has been added, trying to build a kernel loadable module gives a Error 2: no rule to make target 4352. Just indicates that DELL 1550's chipset is not yet supported which contradicts the readme file!

Has anyone has been able to find a linux network driver for Dell Wireless 1550 ?

TIA
