Description FreeDesktop Bugzilla Database Corruption Fix User 2005-06-29 02:52:09 UTC
Hi,

ever since I looked at my XFree86/Xorg logs, I noticed that it displays 
"garbage" for my LCD on this Inspiron 8600 laptop.

(II) RADEON(0): Primary:
 Monitor   -- LVDS
 Connector -- DVI-D
 DAC Type  -- Primary
 TMDS Type -- External
 DDC Type  -- ^A
(II) RADEON(0): Secondary:
 Monitor   -- NONE
 Connector -- VGA
 DAC Type  -- Primary
 TMDS Type -- NONE
 DDC Type  -- VGA_DDC
(II) RADEON(0): PLL parameters: rf=2700 rd=6 min=20000 max=35000; xclk=24300
(WW) RADEON(0): Failed to detect secondary monitor, MergedFB/Clone mode disabled
(==) RADEON(0): Using gamma correction (1.0, 1.0, 1.0)
(II) RADEON(0): Validating modes on Primary head ---------
(II) RADEON(0): Panel ID string: 7T774^D154P1
            
(II) RADEON(0): Panel Size from BIOS: 1680x1050

yes, there is a ^A and a ^D in the strings. Can this be correct?

Yes this is ok.  It could be that the vendor didn't fill in that part of the
bios or it contains garbage data.  I'm going to close this unless you are
actually having a problem with the functionality of the driver.  If so, please
re-open and explain exactly what the problem is.
