Proposing as Alpha blocker due to our criteria. However, please be aware that even if that menu is present, the safe graphics mode never worked properly on UEFI. I believe we really should fix it this time, UEFI machines start to be widely available. But I don't think this needs to block Alpha right now. Final would be enough. The same bug for F19: bug 977816. Rejected for F19, as it seems. Discussed this in the F20 Alpha Go/No-Go meeting [1]. While unfortunate, basic video drivers have not ever worked on UEFI machines and this is not a regression in functionality. Therefore rejected as a release blocking bug for F20 alpha [1] http://meetbot.fedoraproject.org/fedora-meeting-2/2013-09-19/ (In reply to Mike Ruckman from comment #3) I wonder what ajax thinks of this assertion. I've tested the basic video drivers on EFI 1.10 UGA and GOP hardware and they work. UEFI should be significantly more reliable still. Re-proposing for Final. cmurf: I think the note rather means that 'we've never actually provided a working boot menu entry for fallback graphics on UEFI', not that UEFI fallback drivers themselves don't work properly. We really should either a) fix up the UEFI boot menus with a plausible 'fallback graphics' entry, or b) revise the criterion to apply only to non-UEFI boots at present. Indeed, as this bug is bouncing back mostly every single milestone for some time. Can we get more evidence how reliable basic video mode in EFI is? Per ajax at today's blocker review meeting, just passing 'nomodeset' should be sufficient to set 'fallback mode' for UEFI graphics, and should now be the correct way to get 'fallback mode' for BIOS too. So the todo list here is: 1. Drop 'xdriver=vesa' from fallback mode parameters on all bootloaders 2. Add bootloader entry for fallback mode to UEFI live bootloader I can work on that myself. Discussed at 2013-11-13 blocker review meeting - http://meetbot.fedoraproject.org/fedora-blocker-review/2013-11-13/f20-final-blocker-review-1.2013-11-13-17.01.log.txt . Accepted as a blocker per criterion cited in description. I will try to post patches for this. I just checked this, and a Beta live USB stick I have here actually *does* have a Troubleshooting menu with a 'basic graphics mode' option that looks like it would work, when booted in UEFI mode. Kamil, can you look into this a bit more? Did you write your stick with litd or dd or luc or what? In the meantime I can send patches to drop 'xdriver=vesa'. Created attachment 823734 [details]
drop 'xdriver=vesa' from basic graphics mode parameters for live images (patch for upstream livecd-tools)
This patch is against upstream livecd-tools - git://git.fedorahosted.org/git/livecd - and it should drop 'xdriver=vesa' from the parameters used for the 'basic graphics mode' boot on live images.
CCing bcl as he is the owner of upstream livecd-tools. Created attachment 823735 [details]
drop 'xdriver=vesa' from basic graphics mode parameters for lorax-generated images (patch for upstream lorax)
This patch should drop 'xdriver=vesa' for all lorax-generated images, patch is against current upstream lorax master.
I tested F20 Beta x86_64 Live with UEFI boot: cdrom: no safe graphics mode option dd: no safe graphics mode option litd: no safe graphics mode option luc: no safe graphics mode option Adam, are you sure you booted in UEFI mode? Yes, though it's possible that wasn't actually a live image. Just wrote a new stick from the desktop live image and that one doesn't have the troubleshooting menu in it. I'll try and send a patch that adds it today. That patch will remove it from bios. grub in livecd-tools doesn't include the troubleshooting menu, but lmc does. bcl: not quite sure of the significance of your comment, but AIUI, with the patches I've sent so far, all the cases where we actually display a troubleshooting menu with a basic graphics mode option should be 'correct' - they pass 'nomodeset' but not 'xdriver=vesa'. The patch to livecd-tools covers the live-image-booted-BIOS case, and the patch to lorax should cover non-live images whether booted via BIOS or UEFI, unless I missed something. The missing piece is to add the Troubleshooting menu to the grub.cfg generated by livecd-tools' live.py and used by live images booted in UEFI mode, with a correct 'basic graphics mode' entry. I was planning to work on that today - I can see basically how to do it, it's just fairly obvious changes to live.py , but if you want to do it I'm sure you could do it faster than me. Passing nomodeset does not work on two EFI Macs. tty1 hangs at gnome-shell load time, I can switch to a functioning tty2. Fedora 20 beta (final) xorg-x11-server-1.14.3-4.fc20.src.rpm It worked in July when I tested with xorg-x11-server-1.14.2-3.fc19.uefi1.src.rpm from: http://koji.fedoraproject.org/koji/taskinfo?taskID=5596647 https://lists.fedoraproject.org/pipermail/test/2013-July/116930.html Created attachment 824181 [details]
Xorg.0.log gnome-shell failure with nomodeset
Chris: please file a separate bug to avoid confusion. This bug is about providing the option, not troubleshooting cases where booting with the option doesn't work. Created attachment 824183 [details]
make UEFI live boot menu more similar to BIOS and non-live
Can't send patches to anaconda-patches@ for some reason, so continuing to attach here. I have two more patches for livecd-tools that make the UEFI live boot menu resemble the BIOS live and the non-live boot menus better, and add a Troubleshooting submenu with the 'basic graphics mode' entry. Attaching those.

add troubleshooting submenu and basic graphics boot entry to UEFI live boot menu
Assigning to bcl as I've written and provided the patches, up to him to apply, don't think I have the rights. Done. See bug 1030695. lorax-20.4-1.fc20 has been submitted as an update for Fedora 20. https://admin.fedoraproject.org/updates/lorax-20.4-1.fc20 livecd-tools-20.1-1.fc20 has been submitted as an update for Fedora 20. https://admin.fedoraproject.org/updates/livecd-tools-20.1-1.fc20 Package livecd-tools-20.1-1.fc20: * should fix your issue, * was pushed to the Fedora 20 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing livecd-tools-20.1-1.fc20' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2013-21725/livecd-tools-20.1-1.fc20 then log in and leave karma (feedback). Tested F20 TC2 64bit using dd, liveiso-to-disk and livecd-creator with usb stick and brasero with DVD. Both BIOS and UEFI bootloaders have "basic graphics" item in menu with "nomodeset" (and no "xdriver") parameter in kernel lines. To clarify it, I have tested netinst, DVD and Live and all of them have basic video option in bootloader. lorax-20.4-1.fc20 has been pushed to the Fedora 20 stable repository. If problems still persist, please make note of it in this bug report. livecd-tools-20.1-1.fc20 has been pushed to the Fedora 20 stable repository. If problems still persist, please make note of it in this bug report. |
