Description of problem:Since the display's EDID I'm using is not recognized I only see 1024x768 resolution. I followed a guide, installed kernel-docs, compiled the EDIDs, and tried to use 1680x1050.bin. My grub file now looks like this GRUB_CMDLINE_LINUX="rd.lvm.lv=rwvg/usr rd.dm=0 rd.lvm.lv=rootvg/root vconsole.keymap=us $([ -x /usr/sbin/rhcrashkernel-param ] && /usr/sbin/rhcrashkernel-param || :) rd.md=0 rd.luks=0 vconsole.font=latarcyrheb-sun16 rhgb quiet drm_kms_helper.edid_firmware=VGA-1:edid/1680x1050.bin" after the edit I ran: grub2-mkconfig -o /boot/grub2/grub.cfg and rebooted. but the display resolution is still 1024x768. when looking at dmesg it doesn't appear drm is parsed correctly: dmesg |grep Kernel [ 0.000000] Kernel command line: BOOT_IMAGE=/vmlinuz-3.11.10-200.fc19.x86_64 root=/dev/mapper/rootvg-root ro rd.lvm.lv=rwvg/usr rd.dm=0 rd.lvm.lv=rootvg/root vconsole.keymap=us rd.md=0 rd.luks=0 vconsole.font=latarcyrheb-sun16 rhgb quiet drm LANG=en_US.UTF-8. You can see drm_kms_helper.edid_firmware=VGA-1:edid/1680x1050.bin is truncated to drm. bug 901899 was opened and closed for parsing drm so I don't know if this is something new or not. Version-Release number of selected component (if applicable): I just did a yum update of the system. 3.11.10-200.fc19.x86_64 #1 SMP How reproducible: every boot Steps to Reproduce: 1.create edid.bin from kernel-doc 2.move appropriate .bin file to /lib/firmware/edid 3.update kernel command with drm_kms_helper.edid_firmware=VGA-1:edid/<my resolution>.bin Actual results:drm_ is not parsed Expected results:drm is parsed Additional info:
actually in this output drm came from me trying to add the lines manually at boot. In fact drm never shows up in dmesg [ 0.000000] Kernel command line: BOOT_IMAGE=/vmlinuz-3.11.10-200.fc19.x86_64 root=/dev/mapper/rootvg-root ro rd.lvm.lv=rwvg/usr rd.dm=0 rd.lvm.lv=rootvg/root vconsole.keymap=us rd.md=0 rd.luks=0 vconsole.font=latarcyrheb-sun16 rhgb quiet drmLANG=en_US.UTF-8
Please attach your grub.cfg. Is this an EFI system?
Created attachment 834058 [details] grub.cfg's as requested
This is an EFI system and the EFI grub.cfg omits the drm_ changes. I see the issue now. I have to use -o to the EFI grub.cfg.. Let me try that.
updating the EFI grub.cfg with grub2-mkconfig fixed the issue. Thanks for the pointer, please close this out.
This message is a notice that Fedora 19 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 19.

Approximately 4 (four) weeks from now this bug will be closed as EOL if it remains open with a Fedora 'version' of '19'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 19 is 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 change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. 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.
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug.
