Hi, Gentoo.
I'm having trouble with my kernel 4.4.26. It will do everything
expected of it except for running X Windows.
I've checked I've got the kernel configuration set up as described in
the gentoo wiki documents, unless I've overlooked something.
What happens is that I run "startx", and a little while later, the X
server reports that no screens are found.
More precisely, the following appears in Xorg.0.log:
KAVERI, KAVERI, HAWAII, HAWAII, HAWAII, HAWAII, HAWAII, HAWAII,
HAWAII, HAWAII, HAWAII, HAWAII, HAWAII, HAWAII
[ 47.952] (II) modesetting: Driver for Modesetting Kernel Drivers: kms
[ 47.952] (--) using VT number 7
[ 47.963] (II) [KMS] Kernel modesetting enabled.
[ 47.963] (WW) Falling back to old probe method for modesetting
[ 47.963] (EE) No devices detected.
[ 47.963] (EE)
Fatal server error:
[ 47.963] (EE) no screens found(EE)
[ 47.963] (EE)
Please consult the The X.Org Foundation support
at http://wiki.x.org
for help.
[ 47.963] (EE) Please also check the log file at
"/var/log/Xorg.0.log" for additional information.
[ 47.963] (EE)
Note the "No devices detected".
The corresponding piece of the working Xorg.0.log in my older kernel is:
KAVERI, KAVERI, HAWAII, HAWAII, HAWAII, HAWAII, HAWAII, HAWAII,
HAWAII, HAWAII, HAWAII, HAWAII, HAWAII, HAWAII
[ 188.705] (II) modesetting: Driver for Modesetting Kernel Drivers: kms
[ 188.705] (--) using VT number 7
[ 188.713] (II) [KMS] Kernel modesetting enabled.
[ 188.713] (WW) Falling back to old probe method for modesetting
[ 188.713] (WW) VGA arbiter: cannot open kernel arbiter, no multi-card support
[ 188.713] (II) RADEON(0): Creating default Display subsection in Screen
section
"Default Screen Section" for depth/fbbpp 24/32
[ 188.713] (==) RADEON(0): Depth 24, (--) framebuffer bpp 32
[ 188.713] (II) RADEON(0): Pixel depth = 24 bits stored in 4 bytes (32 bpp
pixmaps)
[ 188.713] (==) RADEON(0): Default visual is TrueColor
[ 188.713] (==) RADEON(0): RGB weight 888
[ 188.713] (II) RADEON(0): Using 8 bits per RGB (8 bit DAC)
[ 188.713] (--) RADEON(0): Chipset: "ATI Radeon HD 4550" (ChipID = 0x9540)
Needless to say, the kernel version is the sole difference between the
non-working 4.4.26 and the working 4.0.5.
Would somebody please help me track down this problem. Thanks!
