I've done that, as described in my previous msg, without success. |
| 13 |
|
| 14 |
Then I noticed that Wiki says the kernel needs recompiling |
| 15 |
with 'Drivers->Graphics-><*>DirectRenderingManager |
| 16 |
<*>NouveauCards' ; |
| 17 |
I also unset the "<->Backlight ... " just below, as I don't need it. |
| 18 |
The new kernel is noticeably bigger than the previous version ; |
| 19 |
I copied it to /boot as usual, updated lilo.conf & ran Lilo ; |
| 20 |
the new kernel (called 4.14.52b) booted successfully, |
| 21 |
but neither Nouveau nor Nvidia would start ; |
| 22 |
even worse, neither would start with the previous version 4.14.52 , |
| 23 |
which had been working with Nvidia for some time. |
| 24 |
|
| 25 |
The kernel log stops after several repeats of the lines : |
| 26 |
|
| 27 |
kernel: nvidia: Unknown symbol backlight_device_unregister (err 0) |
| 28 |
kernel: nvidia: Unknown symbol backlight_device_register (err 0) |
| 29 |
|
| 30 |
Finally, I booted into kernel 4.9.95 & Nvidia still starts there. |
| 31 |
|
| 32 |
This is turning into a nightmare. It all started when 4.14.52 |
| 33 |
couldn't find my scanner, which 4.9.16 had no trouble with, |
| 34 |
& then I found I couldn't test 4.9.16, as Nvidia no longer worked with it. |
| 35 |
To test 4.9.16 it seems sensible to try Nouveau instead of Nvidia, |
| 36 |
but that has led to a further tangle. |
| 37 |
|
| 38 |
I suspect the problem with the scanner is that the Epson driver |
| 39 |
needs an update to work with the most recent kernels. |
| 40 |
That's something I'll have to take up with Epson, if I can. |
| 41 |
|
| 42 |
However, the Nouveau/Nvidia mess is something I sb able to sort out. |
| 43 |
Can anyone suggest what's gone wrong & how to put it right ? |
