Comment 1 David Fries 2010-08-05 00:48:30 UTC
Fails for radeon when CONFIG_FB=m. Bad as in most of bootup uses VGA text, then it goes black when switching to the frame buffer until X comes up. Switch to console and the mouse cursor vanishes and the rest of X buffer is unchanged, no text login prompt obviously. So, how do I disable the frame buffer code? CONFIG_FB is forced to at least =m. It's slow as in takes 13 times as long to display a bunch of text, and now doesn't even work. Later when I switch from the console frame buffer to X I get the following message.

Comment 2 Jonathan Dray 2010-08-15 20:23:02 UTC
I have the same issue with a dell studio XPS 1645 and a 1GB ATI® Radeon™ HD 4670 graphics card. I have a black screen on boot since 2.6.34 kernel version. I enabled the "kms by default" kernel option and also have CONFIG_FB set to module. I just tried with a 18.104.22.168 kernel and the situation is unchanged. I'm going to switch CONFIG_FB=m to CONFIG_FB=y and report if it changes the screen's state at boot time.

Comment 3 Jonathan Dray 2010-08-16 00:22:35 UTC
I reconfigured the kernel with option CONFIG_FB=y and recompiled. The newly installed kernel still have the bug and a black screen is diplayed at boot time. The [drm:drm_mode_getfb] *ERROR* invalid framebuffer id error message is still there. I need help on this one.

For a sanity check make sure this is empty, `lsmod |grep fb`. Can you post your kernel configuration, or at least "Graphics support", through "Console display driver support" sections? Did 2.6.33 work, and was it using the frame buffer, or was it using VGA text for console? I was assuming something in Debian changed to enable the graphics console, so I don't think I ever tried making the framebuffer a module before 3.6.35, so I don't know how far back I would need to go to find a good kernel to bisect.

Comment 5 Jonathan Dray 2010-08-17 22:08:31 UTC
I made a few kernel configuration tests and I finally got the init output displayed. It was the CONFIG_FRAMEBUFFER_CONSOLE option that was set to "module". Switching it to "yes" resolved my issue. I don't think it is the Debian kernel configuration default value for that option. I must have changed it when I configured my kernel. I think this have something to do with the early initialisation of the radeon KMS. When the initram is loaded at boot time, the console framebuffer module was not loaded because it is not included in the default module list. Can someone confirm this please ? Thanks for your help.
Comment 6 Florian Mickler 2010-09-07 06:31:05 UTC
If you enable kernel mode setting, the graphics card switches away from "VGA Textmode" into Graphics-Mode. Thus normal text-mode (also known as "vga console") can't be displayed any more and the kernel needs to use a special framebuffer-device to take over rendering of the text-characters into the scan-out-area of the graphics card. For this to work CONFIG_FRAMEBUFFER_CONSOLE and CONFIG_FB has to be enabled. As soon as those 2 are loaded the kernel can display the console again. Does someone in here still has problems? If so, please post your .config. I'm closing this, please reopen if your issue is not solved by enabling the frame buffer console in your .config or if you think there is a Bug/Something that needs to be addressed. Thx, Flo
Comment 7 David Fries 2010-09-09 03:43:22 UTC
CONFIG_FRAMEBUFFER_CONSOLE=m CONFIG_FB=m CONFIG_FB_RADEON=m Fail. Something is loading the radeon module on boot, it looks like when that happens the screen goes black until X starts. I expect the radeon driver is being loaded based on the PCI id. In the kernel configuration, radeon requires fbcon to be compiled, but the radeon module doesn't depend on fbcon, so it isn't loaded. If I manually load fbcon, console starts working again (tested with 2.6.36-rc2+). I'll call the bug that when radeon loads it takes the system from a working text console to a non-working console. I think either radeon should not depend on the framebuffer console, and leave the system in a usable VGA text console mode (my preference since VGA text displays 13 times faster), or the radeon module needs to depend on on fbcon so fbcon gets loaded and moves the system from a working VGA text console to a working frame buffer console. In the kernel configuration, DRM_RADEON requires DRM_KMS_HELPER DRM_KMS_HELPER requires FRAMEBUFFER_CONSOLE
Comment 8 Florian Mickler 2010-09-09 04:54:25 UTC
Make sure the CONFIG_FB_RADEON doesn't get loaded. I don't know if it is handled gracefully nowadays, but in the early days of kernel modes setting that would clash. (CONFIG_FB_RADEON is the old Framebuffer driver which should be deactivated as the new KMS radeon driver substitutes for it, providing a framebuffer device itself.) Other from that, I'm not exactly sure why the display goes black. I'm reopening the bugreport until this is resolved. There probably is also a way to tell the radeon driver to not switch the mode. Perhaps via the video= kernel commandline?
Comment 10 David Fries 2010-12-11 21:16:11 UTC
Created attachment 39872 [details] patch to load the fbcon This solves compiling CONFIG_FB=m and being left with a blank screen because the radeon module is automatically loaded, but fbcon isn't. If radeon had to be manually loaded, then it would be the user's fault for not loading fbcon as well, but as radeon is being loaded automatically, there isn't much a user can do from console to even fix it. More bug details from here, https://bugzilla.kernel.org/show_bug.cgi?id=16221 Does this look like a reasonable solution? Should it bother checking find_module first?
Comment 11 Florian Mickler 2010-12-12 16:56:09 UTC
hi, david! + const char *namue = "fbcon"; You typoed an u in there..? Maybe you should also post that patch to lkml and the drm mailinglist for comments and review? I'm not shure the relevant people notice it here in this bugzilla. (I think this is a reasonable idea. Not shure what the drawbacks are.)
