 Posted: Sun Feb 02, 2025 8:55 am Post subject: framebuffer not working in new installation |
 |
|
I'm installing gentoo on a cherrytrail tablet, I cannot however seem to be able to get the framebuffer working so I can debug kernel panic issues, if I use the livecd kernel and initrd framebuffer works fine and so does the root file system mounting, so it looks like a kernel config issue.
dmesg from the livecd:
| Code: | [ 0.753010] efifb: probing for efifb
[ 0.753133] efifb: framebuffer at 0xc0000000, using 1876k, total 1875k
[ 0.753177] efifb: mode is 800x600x32, linelength=3200, pages=1
[ 0.753208] efifb: scrolling: redraw

[ 0.754045] Console: switching to colour frame buffer device 100x37
[ 0.758452] fb0: EFI VGA frame buffer device |
complete dmesg:

I did do a make oldconfig, very strange!.
anyway I removed the config altogether and tried running the defconfig, I enabled the 3 frambuffer options in the wiki(efi,vesa and vga16) and I am still getting the same result, I do not think it is related to the framebuffer config at all now.
yes I have left out alot of kernel options that I intend to add later once I have the macine booting, it is a pain to get anything done on this machine at the moment. |
