Fedora Core (GNU/Linux) on the Dell Latitude X1

	Hard drive : Toshiba 60GB UDMA100	Working flawlessly, 21MB/s
	Optical drive : D-Bay Samsung CDRW/DVD SN324S	Installed fine from it. When booting with it connected, it appears as an IDE drive, and when hot plugging it, as a usb mass storage device, very practical
	USB : USB 2.0, EHCI 1.00	Works fine with default usb-uhci and ehci_hcd
	IEEE1394 Firewire	Works fine with default video1394 and raw1394
	GigabitEthernet : Broadcom BCM5751 (Tigon3)	Works fine with the default tg3 driver
	Sound chip : Intel 82801FB AC'97	Works fine with the default ALSA snd_intel8x0m module
	Video controller : Intel Mobile 915GM	Used vesa in xorg-x11 6.8.2, but i810_drv driver in 7.0.0
	LCD display : 1280x768	Works at full 1280x768 using the 855resolution utility
	Wireless : Intel PRO/Wireless LAN 2200BG	Works fine with ipw2200 module and ipw2200-firmware
	Bluetooth : Dell Truemobile	Connected internally to the USB bus, works great
	Modem : Broadcom or Conexant	These little beasts simply suck...
	Secure Data slot	Ricoh device not internally USB connected, would require a specific driver
	Compact Flash / MMC slot	On a Cardbus bridge, works with the pcmcia service and cardmgr

• Green : Works with what is provided in Fedora Core
• Orange : Works, but with third party utilities or drivers
• Red : Doesn't work

Display :

Fedora Core 5 should not have any problem with the resolution, but I only installed Fedora Core 4, which worked only with the vesa driver at 800x600. It could also work at 1024x768 but you got a streched display. Recompiling xorg-x11 from CVS was required in order for the i810 driver to recognize the card and provide accelerated display. The other option was to replace the i810_drv.o file, but text consoles broke unless fb was used and you needed to change HorizSync to 20-90, VertRefresh to 60-100 and add this line to the Monitor section of xorg.conf :

ModeLine "1280x768" 111.69 1280 1336 1616 1728 768 770 782 808

For a 1024x768 framebuffer console, you can append this to your grub.conf kernel lines :

vga=0x317 video=i810fb:vram:2,xres:1024,yres=768,bpp:24,hsync1:30,hsync2:49,vsync1:40,vsync2:70,accel,mtrr

I've tested the VGA output, and it works fine as long as you boot with the external VGA connected and switch to it before X starts, using Fn+F8.

Suspend :

Suspend (S3) works great with recent Fedora Core 4 kernels (it used to not work, then the tg3 network interface wouldn't work anymore after a resume), so probably with Fedora Core 5 too, by using Fn+Esc. The only catch is that the backlight doesn't turn back on alone, you need to use Fn+Up or Fn+Down and change the screen luminosity for it to turn back on.

Overall this is an impressive laptop, I really love it.
