Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information especially concerning your hardware we require that will be helpful in our diagnosis of this issue. Please install Fedora with a basic video driver, remove /etc/X11/xorg.conf, remove nomodeset and xdriver parameters from the kernel command line, and add 3 to the kernel command line. Then run startx command as normal (non-root) user. Whether it fails or not, still /var/log/Xorg.0.log and the output of dmesg program from the failed attempt to start X would be useful. We will review this issue again once you've had a chance to attach this information. Thank you very much in advance. Unless I blacklist the i915 driver, I get no video. Also, booting at initlevel 3 gives me no visible prompt (although I can blind-type and things work). This is consistent with how the system is generally working with my normal install; X works but the virtual consoles do not. I ssh'd in and ran startx (WITH the i915 blacklisted). Attached are the results. Created attachment 486863 [details]
Xorg.0.log
As requested.

dmesg output
Any news about it? I'm facing the same problem and I'm willing to help debugging the problem. It turns out the hardware setup is an example of "Hybrid Graphics"; it's designed to use the Intel chipset on boot and when sans power cord, and the ATI chipset when plugged in. Neither chipset is supported in Fedora 14. I upgraded to Fedora 15Beta, and that gets me working Intel graphics with acceleration (at the cost of needing to suffer Gnome3). I'm sure the ATI drivers will be along sometime; I'm happy for now. This message is a notice that Fedora 14 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 14. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '14' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 14 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping |
Created attachment 486487 [details] lspci -v output Description of problem: The ATI Radeon HD 6850M in my HP Envy 3D 17" will not function at all without some tweaking and is unsupported by the radeon driver. Version-Release number of selected component (if applicable): 6.13.1 (I also tried Fedora 15 Alpha, with the same results) How reproducible: 100% Steps to Reproduce: 1. Boot system Additional info: The installer won't work except in basic video mode, which uses "nomodeset" as a kernel argument and sets the system into VESA mode. Removing nomodeset causes the system to boot without video (the system seems happy when remotely accessed). lspci shows that there's another VGA chipset in the system (intel); this is not advertised in the system specs and is probably not meant to be used, but it cannot be disabled in the BIOS utility. By blacklisting that driver with "rdblacklist=i915", I can remove "nomodeset" from the kernel arguments and the system boots with video, but still in VESA mode. Explicitly telling Xorg to use the radeon driver (with an xorg.conf) results in X failing to find any hardware it can use and failing to start (again, no video, but examinable by ssh'ing in). I tried these same steps on a F15Alpha liveCD, in the hopes that a more recent driver would spot the hardware (with the i915 blacklisted), but saw similar results. I also tried the proprietary drivers (with F14) as packaged by RPMFusion, but had no luck with them. Until this is fixed, I am stuck at 1280x1024 rather than the native resolution of 1920x1080 Please find attached the output of "lspci -v".
