 Posted: Mon Nov 12, 2007 7:26 pm Post subject: [SOLVED] uvesafb does not work |
 |
|
Hey,
I have a problem with my (new) laptop and the framebuffer.
The laptop is a Hp omnibook xe4500 with an ali chipset and an ATI Mobility M6 LY gpu.
The problem is that the vesafb can't display the default resolution of 1400x1050 and is very slow,
randeonfb strikes completly - so i set all my hope to uvesafb.
The Kernel i use is 2.6.23-gentoo-r1.
As the point uvesafb starts, the screen is black and doesn't came back (in the back he finished booting).
my grub.conf:
| Code: |
kernel /vmlinuz-2.6.23-gentoo-r1 root=/dev/hda3 video=uvesafb:640x480-16,mtrr:1,ypan
|
cut of kernel config:
| Code: |
CONFIG_INITRAMFS_SOURCE="/usr/share/v86d/initramfs"
CONFIG_INITRAMFS_ROOT_UID=0
CONFIG_INITRAMFS_ROOT_GID=0
CONFIG_CONNECTOR=y
CONFIG_FB_UVESA=y
CONFIG_INITRAMFS_SOURCE="/usr/share/v86d/initramfs"
CONFIG_FRAMEBUFFER_CONSOLE=y
|
Here a short cut from dmesg:
| Code: |
uvesafb: ATI Technologies Inc., R100, 01.00, OEM: ATI MOBILITY RADEON, VBE v2.0
uvesafb: protected mode interface info at c000:5243
uvesafb: pmi: set display start = c00c52d7, set palette = c00c5323
uvesafb: pmi: ports = 9010 9016 9054 9038 903c 905c 9000 9004 90b0 90b2 90b4
uvesafb: no monitor limits have been set, default refresh rate will be used
uvesafb: scrolling: ypan using protected mode interface, yres_virtual=9187
Switched to high resolution mode on CPU 0
uvesafb: mode switch failed (eax=0x4f02, err=1)
Console: switching to colour frame buffer device 80x30
uvesafb: framebuffer at 0xe8000000, mapped to 0xf8880000, using 11484k, total 32768k
fb0: VESA VGA frame buffer device
|
klibc is re-emerged and v86d too.
I tried most of the possible resolutions and options related to uvesafb (grub.conf)
thanks for your help

thx,
i read this post, but i think this CONSOLE= option is splash related,...
i tried it anyway, but it doesn't help.
i get the same error, i think this is the importend line:
| Code: |
uvesafb: mode switch failed (eax=0x4f02, err=1)
|
but i didn't find anything about this "err=1",... |

Well, let's follow along with their thread in ours. Please post the output of:
| Code: | | cat /sys/bus/platform/drivers/uvesafb/uvesafb.0/vbe_modes |

The output confirms your BIOS supports the mode you want:
| Code: |
1400x1050-8, 0x0140
1400x1050-15, 0x0141
1400x1050-16, 0x0142
1400x1050-24, 0x0143
1400x1050-32, 0x0144
|
Let's start at the beginning:
| Code: | | emerge -C gentoo-sources && emerge --sync && emerge gentoo-sources |
This will remove your current kernel, update, and re-install it. DO NOT select anything having to do with the framebuffer. After we get your system working with a clean kernel, we will start adding the framebuffer back in.

| Code: |
#

# CONFIG_VIDEO_OUTPUT_CONTROL is not set
CONFIG_FB=y
# CONFIG_FIRMWARE_EDID is not set
# CONFIG_FB_DDC is not set

# CONFIG_FB_TILEBLITTING is not set
|
Assuming you took out framebuffer support, and this config is from November 11, 2007, now set CONFIG_FB=y, along with CONFIG_FIRMWARE_EDID=y
This will let the kernel access your video BIOS, and grab an auto-computed resolution. We then will add:
| Code: |
#
# Frame buffer hardware drivers
#
# CONFIG_FB_CIRRUS is not set
# CONFIG_FB_PM2 is not set
# CONFIG_FB_CYBER2000 is not set
# CONFIG_FB_ARC is not set
# CONFIG_FB_ASILIANT is not set
# CONFIG_FB_IMSTT is not set
# CONFIG_FB_VGA16 is not set
CONFIG_FB_UVESA=y
...
# CONFIG_FB_RADEON is not set
...
|
Disable UVESA and enable Radeon.
Rebuild your kernel, and reboot, and tell me if you get a framebuffer at all. Right now were testing to see if any framebufer works.

ok,
here's the new config
and this is from dmesg:
| Code: |
radeonfb: Retrieved PLL infos from BIOS
radeonfb: Reference=27.00 MHz (RefDiv=60) Memory=166.00 Mhz, System=166.00 MHz
radeonfb: PLL min 12000 max 35000
Non-DDC laptop panel detected
radeonfb: Monitor 1 type LCD found
radeonfb: Monitor 2 type no found
radeonfb: panel ID string: Samsung LTN150P1-L02
radeonfb: detected LVDS panel size from BIOS: 1400x1050
radeondb: BIOS provided dividers will be used
radeonfb: Dynamic Clock Power Management enabled
radeonfb (0000:01:00.0): ATI Radeon LY
|
Framebuffer works, but only with 640x480 |

I think we need to add:
| Code: |
#
# Console display driver support
#
CONFIG_VGA_CONSOLE=y
# CONFIG_VGACON_SOFT_SCROLLBACK is not set
# CONFIG_VIDEO_SELECT is not set
# CONFIG_MDA_CONSOLE is not set
CONFIG_DUMMY_CONSOLE=y
# CONFIG_FRAMEBUFFER_CONSOLE is not set
# CONFIG_LOGO is not set
|
CONFIG_FRAMEBUFFER_CONSOLE=y, CONFIG_LOGO=y and CONFIG_VIDEO_SELECT=y
CONFIG_FRAMEBUFFER_CONSOLE initializes the framebuffer using the driver we selected.
CONFIG_LOGO draws a penguin in the upper left corner.
CONFIG_VIDEO_SELECT lets the framebuffer select the video mode.
CONFIG_VIDEO_SELECT will be selected via your EDID settings. (post above)

I use the radeonfb, and it works.
it can display the right resolution, and there are no problems with DRI under X. |

And.... what about suspending?
Does it resume?

sry, i didn't know.
I've never tried suspending on this machine, but it's a good idea ;o)
When there's a little bit of freetime, i will try it and post it here.
ciao
