Red Hat Bugzilla – Bug 118211
does not configure my laptop screen correctly---ddc probe not complete
Last modified: 2007-11-30 17:10:38 EST
Description of problem: anaconda/kudzu still does not do the ddc probe correctly to be able to configure XFree86 to work on my laptop. Version-Release number of selected component (if applicable): Linux version 2.6.3-2.1.253 (bhcompile@porky.devel.redhat.com) (gcc version 3.3.3 20040216 (Red Hat Linux 3.3.3-2.1)) #1 Tue Mar 9 13:35:40 EST 2004 kudzu-1.1.51-1 How reproducible: everytime Steps to Reproduce: 1.do a install 2. 3. Actual results: can't identify screen Expected results: it configures XFConfig correctly. Additional info: With every version starting at 9 I have to manually configure XFree86 to make my laptop screen work correctly. Also the r128 may have problems also--not sure--I have learned to always use vesa or my screen may go white and lock my machine up. mharris has been saying over the past two years he can not identify with hardware--dell or redhat should help their engineers--it is impossible for them to do their job without proper support.
Can you attach an XFree86.log? We do some log parsing to try to auto-setup LCDs but it's possible the output has changed subtly.

I need a log when running with the ati driver, not the vesa driver. The vesa driver doesn't have the card-specific knowledge to do bit twiddling and determine what the TFT is. Also, 'Option "nodri"' in the video card section is likely to be effective at fixing your problems with the screen going white and not coming back while not having the performance penalties associated with the vesa driver.
do you want the ati driver OR the r128. r128 has been the driver that was used in the past.
just tried again using the 'Option "nodri"' option---No luck--screen still goes white when logging out
Created attachment 98548 [details] here is the log for the r128 driver my screen now will not go down to 1024x768 resolution even though in the display program it says 1024x768.
Created attachment 98549 [details] attached is a manually modified config file Look at what i had to do with the vertical refresh and horizsync upper limits to get the screen to do 1024x768. Also had to reduce colors from 24 bit to 16 bit. The config program does not figure any of this out. You have to manually do it. I have sent XFConfig files to about 30 people over the last year who have the c800 dell laptop -- all having the problem with the screen. I hope you can fix it. Somehow windows does it correctly.
