Black screen when starting X

[sorenhjelm]

I just installed PCBSD on a laptop:

-------------------------------------------------
AcerTravelmate 4601WLMI
1.6 GHz, 533 MHz FSB, 2MB L2 Cache
15.4" WXGA wide TFT LCD 60HZ
ATI Mobility Radeon X700
PCI Express with 64 MB VRAM
60 GB HHD
512 MB DDR2
Intel PRO/Wireless 2200 BG Network connection
------------------------------------------------

When I installed PCBSD I had to choose "reset to default VESA driver" for the graphical installation to start, othervise the screen turned black.
When everything was installed, I rebooted the system. The "PCBSB screen" shows up, but when KDE is about to start, the screen turnes black.

If I connect another(analog) screen to the laptop, everything looks fine. KDE stats. I have been surfing around looking at peoples xorg.conf files,
and changing HorizSync, VertRefresh, resolutions etc. Nothing seem to work, the TFT screen on the laptop remains black. On the connected screen
you can see the results, when changing in xorg.conf however.

An other problem is that the wireless network card is not detected.

For the Wifi:

Open the /boot/loader.conf file as root in a text editor like kwrite e.t.c. and add these lines to the bottom of it. (Copy and paste if you want) & Save the file.


# Intel 2200 Wifi card
if_iwi_load="YES"
if_wlan_acl="YES"
if_wlan_ccmp="YES"
if_wlan_tkip="YES"
if_wlan_wep="YES"
if_wlan_xauth="YES"


The card may need firmware (http://damien.bergamini.free.fr/ipw/) before it will work. If you use encryption I'd suggest WPA-PSK of applicable.

(Assuming you use DHCP on the router) Add

ifconfig_iwi0="WPA DHCP"


To the bottom of the /etc/rc.conf file and create a /etc/wpa_supplicant.conf file like this.


network={
ssid="Your Networks SSID/Name"
scan_ssid=1
key_mgmt=WPA-PSK
psk="very secret passphrase"
}

you'll have to specify

HorizSync 31.5 - 48
VertRefresh 43 - 60


to your /etc/X11/XF86Config in the "Monitor" section. otherwise, no matter what resolutions you specify, it won't use your settigns.

the settings above are conservative, for a monitor that supports 1024x768@60 top. (i'm not sure about the 48kHz value though...)

USE THE SETTINGS CAREFULLY! so you have been warned...

Thanks for the Wifi!

The screen problem unfotunately remains. It seems that the LCD screen on the Laptop can't be found. I have defined two two screens in xorg.conf, setting one as primary.

When checking Xorg.0.log only the extern screen can be found eith VGA connection, the secondary screen (i.e. the laptop screen) with LVDS connection can't be found. Dac-type unknown. Why can't taht screen be found, it doesnt matter if I change mode to VESA, implying that it isn't a driver problem?

I'm having the same problem with my Dell Latitude 610., Except that I didn't test on another screen and didn't have reset X to VESA when installation starts. Everything looks fine before KDE starts and then it just turn black~

Try reading my first post on this page (http://forums.pcbsd.org/viewtopic.php?t=6856&postdays=0&postorder=asc&start=15), you will need to go into the console as single user, mount the drive and edit your video configuration file changing the video driver to vesa and hopefully that will work.
