Hi, Gentoo. |
| 2 |
|
| 3 |
I'm having trouble with my kernel 4.4.26. It will do everything |
| 4 |
expected of it except for running X Windows. |
| 5 |
|
| 6 |
I've checked I've got the kernel configuration set up as described in |
| 7 |
the gentoo wiki documents, unless I've overlooked something. |
| 8 |
|
| 9 |
What happens is that I run "startx", and a little while later, the X |
| 10 |
server reports that no screens are found. |
| 11 |
|
| 12 |
More precisely, the following appears in Xorg.0.log: |
| 13 |
|
| 14 |
KAVERI, KAVERI, HAWAII, HAWAII, HAWAII, HAWAII, HAWAII, HAWAII, |
| 15 |
HAWAII, HAWAII, HAWAII, HAWAII, HAWAII, HAWAII |
| 16 |
[ 47.952] (II) modesetting: Driver for Modesetting Kernel Drivers: kms |
| 17 |
[ 47.952] (--) using VT number 7 |
| 18 |
|
| 19 |
[ 47.963] (II) [KMS] Kernel modesetting enabled. |
| 20 |
[ 47.963] (WW) Falling back to old probe method for modesetting |
| 21 |
[ 47.963] (EE) No devices detected. |
| 22 |
[ 47.963] (EE) |
| 23 |
Fatal server error: |
| 24 |

| 26 |
Please consult the The X.Org Foundation support |
| 27 |
at http://wiki.x.org |
| 28 |
for help. |
| 29 |
[ 47.963] (EE) Please also check the log file at |
| 30 |
"/var/log/Xorg.0.log" for additional information. |
| 31 |
[ 47.963] (EE) |
| 32 |
|
| 33 |
Note the "No devices detected". |
| 34 |
|
| 35 |
|
| 36 |
The corresponding piece of the working Xorg.0.log in my older kernel is: |
| 37 |
|
| 38 |
KAVERI, KAVERI, HAWAII, HAWAII, HAWAII, HAWAII, HAWAII, HAWAII, |
| 39 |
HAWAII, HAWAII, HAWAII, HAWAII, HAWAII, HAWAII |
| 40 |
[ 188.705] (II) modesetting: Driver for Modesetting Kernel Drivers: kms |
| 41 |
[ 188.705] (--) using VT number 7 |
| 42 |
|
| 43 |
[ 188.713] (II) [KMS] Kernel modesetting enabled. |
| 44 |
[ 188.713] (WW) Falling back to old probe method for modesetting |
| 45 |

| 46 |

| 47 |

| 48 |

| 49 |

| 50 |

| 53 |
[ 188.713] (--) RADEON(0): Chipset: "ATI Radeon HD 4550" (ChipID = 0x9540) |
| 54 |
|
| 55 |
|
| 56 |
Needless to say, the kernel version is the sole difference between the |
| 57 |
non-working 4.4.26 and the working 4.0.5. |
| 58 |
|
| 59 |
Would somebody please help me track down this problem. Thanks! |
