Red Hat Bugzilla – Bug 26295
XFree does fall back to FBDEV on FSC Laptop
Last modified: 2007-04-18 12:31:14 EDT
I did a fresh install on a Fujitsu Siemens Laptop with Neomagic video card
It detected everything right and did a monitor check and detected the LCD.
Resolution was set to 1024x768
After reboot it came up with 800x600 and FBDEV driver
The neomagic driver did not find a valid modeline because the VSYNC range
was very narrow.
I will post additional information this evening (forgot the data sheet at
We (Red Hat) should really try to fix this before next release.
Did you get a chance to get your data sheet together? We have a couple of
laptops here with NeoMagic chips, and they behave okay. I'd like to track down
the problem you are having.
Sorry for the delay...
Here comes more data:
The laptop is a Siemens Scenic Mobile 510 AGP
lspci says for the vga chip: Neomagic Corporation [MagicMedia 256AV] (rev 20)
And the installer detected via DDC:
The Hsync range was to small to get a valid modeline for 1024x768.
After increasing this to 31.5-70 it works.
