[SOLVED] Boot Resolution with Intel Haswell GPU and KMS

Dear All,
     This thread is a follow up of this one: https://bbs.archlinux.org/viewtopic.php?id=189562. I created a new thread as I think the focus of the problem has shifted and the old title might be misleading and lead to helpful people ignoring the thread. I hope this is ok. Please correct me if I did not behave correctly.
I think most of the "flashes" I see come from X switching from native resolution (3200x1800) which is used when starting, to 1920x1080, which I set in the configuration file.
So my question is: how can I have the 1920x1080 resolution at boot (i.e. during early boot, using the KMS and including the i915 driver in mkinitcipo?):
I tried:
1) Creating the configuration file in xorg.conf.d and including it into the mkinicpio
2) Setting the GRUB_GFX_MODE
3) Using the EDID method (with built-in resolution 1920x1080) as described here: https://wiki.archlinux.org/index.php/ke … s_and_EDID
4) Using uvesafb as described in the WIKI: https://wiki.archlinux.org/index.php/uvesafb
Nothing worked. X starts during boot always with the same native resolution, the switches to 1920x1080 when GDM starts. Can you please suggest a method to set the boot resolution? It is for sure technically possible as Ubuntu does it when installed on the same hardware.. I think I just haven't found a way...

Ok, answering my own question, it would appear that adding video=1920x1080 does the trick. However, I still see a lot of flashing (I think that people call it flickering)

  • I have a MacBook Pro with Intel Core Duo and Snow Leopard 10.6.8. Want to upgrade to Lion to take advantage of icloud. Is there anything I can do without getting a new MacPro?

    I have a MacBook Pro with Intel Core Duo and Snow Leopard 10.6.8. Would like to upgrade to Lion but it requires a minimum of Intel Core 2 Duo. Can I get what I need or do I have to buy new MacBok Pro?

    I also have a core duo MBP with Snow Leopard and it runs perfectly.  There are very few things it cannot do as compared to the faster, newer MBPs, but that is attributable to the CPU, not the OS.  There are some who view Lion as downgrade rather than as an improvement.  If there are important applications that reqire a fast CPU or Lion features that you find essential, by all means get a new MBP.
    I have an aphorism:  Obsolescence is more often a perception rather than a reality.  Besides the silver keys look much classier than the black ones.

    Hi cybertoof,
    Welcome to Apple Support Communities.
    It sounds like you're seeing a startup issue with your Mac, it's booting to a gray screen with an Apple logo. Try the suggestions in the article linked below, they will resolve most issues related to starting up your Mac.

  • Intel Haswell GPU acceleration in CC?

    Has anyone tried Intel Haswell integrated graphics chips for GPU acceleration in Adobe Premiere Pro CC? If so: cigar? No cigar?
    (I realize Haswell is neither supported nor is anywhere in the same performance bracket with discrete desktop GPUs from AMD and NVidia, and clearly isn't going to make you return your GTX-Titan. Just curious if GPU acceleration is at all possible given Haswell's hardware support for OpenCL and other neat tricks.)

    Premiere Pro CC cannot use Intel graphics for hardware acceleration.
    Guess things change pretty fast in Adobe town...

  • Boot issues with x79a-gd45 (8d) and n680gtx 4gd5/0c no bios splash screen

    I have system
    with
    x79a-gd45 (8d) and
    n680gtx 4gd5/0c
    16gb ram out of 4 modules
    vertex3 ssd
    win7 64 en updated everything to the latest version.
    during boot i get b2 b4 and 92 messages but not bios splash screen.
    When doing a test with an old ati card the system shows splah screen all is fine.
    I have 4 systems like this all behaving the same
    any ideas

    Hello I updated the bios, was not neccesarry but problems remains.
    cleared the cmos several times.
    I have to inform you that i'm building 4 similar systems all suffering from the same problem.
    During boot there is a black boot screen not splash screen. and on the top left a cursor and in the bottom right b2 b4 and 92 messages.
    When I install and old ati x1050pro all is ok during boot I see the splash screen and i'm able to enter the bios.
    boot time approx 20 sec.
    when running the system with the msi n680gtx boot times are back to 2 min and a long period with only the black boot screen and the bios codes.
    As suggested I tested the card in a other system.  Motherboard is asus. And voila I get a splash screen.
    STRANGE THING IS THAT THIS SCREEN IS NOT RESISED BUT IS I GUESS 800 X 600 AND CENTERED IN THE SCREEN.
    Also after several reboots I could not get a screen filled splash screen.
    Can this be a video card bios issue ?

  • [Solved] Login freezing with busy mouse cursor and black screen.

    After installing some recent updates I have suddenly found a problem when starting the login manager for Cinnamon.
    After booting I am greeted with a black screen and a "busy" mouse cursor - like a stopwatch. I can't ctrl-alt-backspace to restart X.
    What fixes it is - if I ctrl-alt-F2 to a new console and kill -9 the Xorg process. This causes X to restart normally. I have to do this every time now
    I don't know if this is systemd related or what, but it only seemed to happen after the updates below.

    Thanks for your help.
    I don't know the details to be honest, but the title of your post basically describes my situation with GDM when I used accountsservice >0.6.25, so I figured it was worth a shot, since the symptoms were the same.
    Also, Cinnamon depends on accountsservice if I'm not mistaken, so it didn't seem unreasonable that the update broke Cinnamon too.
    I'm glad it works now. Let's hope a updated, working version of accountsservice is released soon.

  • [Solved] No audio with Intel HDA

    I can't seem to get audio on my fresh (first) install of Arch. I had sound when I had ubuntu/trisquel installed, but when I switched to archlinux I can't seem to figure how to get it to work.
    I have already unmuted my speakers/etc. in alsamixer. I can hear my system beep/makerandomnoises when I, for example, try to hit tab/autofill and nothing is there to fill in terminal; or when I try to backspace and there is nothing left to delete and it results in a beep (not sure if that matters).
    The sound cards that alsamedia shows are; Intel HDA PCH, and Intel HDA HDMI.

  • Mupen64plus on intel w/ dri2 and kms

    well i can't play any games into mupen and i'm really out of clues, the only thing i'm getting from running in console is the following output
    http://paste-it.net/public/je2cbc9/
    so if anyone could help me i would then be happily playing
    btw i use a 945gms w/ dri2 uxa and kms enabled, w/ no xorg.conf

    I think I know what the problem is ...
    So you have Mac OS 10.5.1 ... that's Darwin 9.
    But your dev tools came with Darwin 8 ... 10.4. I mean, what's going on is that the linker is trying to link the System.dylib to your code using the Darwin 8 System.dylib. It opens the dylib, but hates what it finds in the Mach-O _TEXT_ section.
    So, I bet you had a 10.4 machine, installed the 10.4 dev tools at some point, upgraded the machine to 10.5, but you haven't yet installed the 10.5 dev tools.
    My bet is that if you install the 10.5 dev tools, you should be okay. Woolamaloo uses the same C code ... and it does compile in 10.5 using the 10.5 dev tools. Honest.

  • [Solved] 1366x768 Resolution with nVidia drivers

    I am trying to set up my monitor at full resolution (1366x768) and I am having issues getting it to display correctly. Out of the box, I was able to get 1024x768, but when I tried to manually set the full resolution using xrandr, it will only go up to 1280x768 with a black bar on the right. Below are the relevant files;

    Any suggestions?

    Drop that xorg.conf completely, it doesn't contain any relevant settings. The problem is that the driver can't get the display's EDID:

    Try a different cable. Or, if you can, use a digital connection (DVI, HDMI) instead of VGA.

  • Laptop intel 4000 gpu and nvidia 675m offer same performance?

    in photoshop...particularly when rendering 3d extrusions they both do the same time rendering a layer.  obviously i can force photoshop to use either gpu.  the 675m is a heck of a lot more powerful than the integrated intel gpu. 
    any special trick to make it render faster using the nvidia as opposed to the intel?

    The concept of a dual GPU laptop is that the embedded Intel GPU will come into play, when you are on the battery, doing very low-level and general computing, and it will save battery life.
    In a perfect world, when using higher-intensity programs, such as Ps, the nVidia, or AMD/ATI GPU will automatically come into play, giving you greater performance. That is not always the case, but is what is intended.
    With a program, such as Ps, you will not be using both GPU's for any process - it's one, or the other.
    Good luck,
    Hunt

  • [Solved] Boot process hangs for installed Arch and installation usb

    Hi. I've been using Arch Linux for around 6 months now and I'm in love with it. It is now my primary OS. However, I might have done something or performed some update, and I can no longer boot into Arch. The boot process hangs right before it should show the login screen (I'm using Gnome 3.6 with GDM). I see the following messages on the screen:
    Loading Linux core repo kernel ...
    Loading initial ramdisk ...
    /dev/sda3: recovering journal
    /dev/sda3: clean, 330610/1749664 files, 5585671/6996827 blocks
    And then it hangs right there. I have to hard-reboot after this.
    I then tried to boot using the Arch Linux Installation USB (archlinux-2012.12.01-dual.img), which also hangs at a particular point, before it should show me the prompt. I took a picture of the screen where it hangs: Screen Capture. This is an issue with just my laptop, because the USB boots just fine on another laptop I tried.
    I also have Windows 7 and Ubuntu 12.10 installed on my system, and I'm able to boot into both of them.
    I have 2 hard drives: /dev/sda is a 120GB SSD, and /dev/sdb is a 500GB hard disk. My partitions are as follows:
    sda1 - Windows 7 100MB System Reserved Partition (boot flag enabled)
    sda2 - Windows 7 OS
    sda3 - ArchLinux (boot flag enabled)
    sdb1 - Ubuntu 12.10 (boot flag enabled)
    sdb2 - Just data
    I ran bootinfoscript and below is the output:

    Ok.. So my Arch Linux randomly decided to work. I'm sure I didn't do anything between my last "not working" state and my current "working" state. Below are a few things I tried:
    I thought of trying an earlier build of ArchLinux, and downloaded archlinux-2012.11.01-dual.iso and made a bootable USB out of it. It still hung.
    I was getting error messages during Arch boot that the last access time for the disks was at a future date. I found out that Ubuntu was using localtime instead of UTC and screwing up my hardware clock. I fixed it, and thought maybe the time issues were causing the boot problem. But fixing time didn't solve my problem.
    I chrooted into Arch from my Ubuntu install, ran 'sudo pacman -Syyu' and updated my Arch install.
    I thought maybe GDM isn't starting up. I re-enabled the service using 'systemctl enable gdm.service'.
    I removed OpenNTPd and installed NTPd. Enabled the daemon using 'systemctl enable ntpd'
    None of the above solved the problem, and rebooting to Arch still hung the system. So I stopped fiddling with it yesterday. Today, as usual, I just tried logging into Arch.. And it just worked out of the blue. The solution to me is as mysterious as the problem.
    I told this to my friend who introduced me to Arch, and this is what he said:
    Damn it computers, you were supposed to be deterministic!

  • [SOLVED] Boot fails with "ata4: SRST failed (errno = -16)"

    I have desktop that has four disks. They have similar three partitions sitting on RAID.
    /boot and swap are on RAID1
    / is on RAID5.
    This worked well until a couple of weeks ago I noticed I couldn't connect to it via SSH. I went onsite and the desktop was humming but I couldn't get picture on the screen and alt + sysrq + REISUB did nothing. I shut it down by pressing power button and started it again. It gave me following errors:
    ata4: SRST failed (errno = -16)
    After a while there was
    reset failed, give up
    I restarted the machine and went to BIOS. There was only two of four disks visible. I shut the computer down, removed the power cord and then plugged it back in. This time BIOS showed all the disks there. I tried to boot up Arch and got the following.
    Booting the kernel.
    running early hook [udev]
    running hook [udev]
    Triggering uevents
    mounting '/dev/md3' on real root # md3 is the RAID 5 device containing root
    mount: you must specify the filesystem type
    You are now being dropped into an emergency shell.
    sh: can't access tty; job control turned off
    After that I tried to chroot from USB installation disk. First I check the RAID devices and see that in md1 (/boot) all seems to be ok. In md2 (swap) half of the partitions are missing. I'm not sure how to interpret the last one.
    cat /proc/mdstat
    Personalities : [raid1]
    md1: active raid1 sdd1[3] sdb1[1] sda1[0] sdc1[2]
    1048564 block super 1.0 [4/4] [UUUU]
    md2: active raid1 sdb2[1] sda2[0]
    2096116 block super 1.2 [4/2] [UU__]
    md3: inactive sdb3[1](S) sda3[0](S) sdd3[4](S) sdc3[2](S)
    608169984 block super 1.2
    unused devices: <none>
    I remove those devices and try to recreate them. md1 says it starts with four drives. md2 starts with 2 driver out of 4. And then the last one.
    mdadm --assemble /dev/md3 /dev/sd[a-d]3
    mdadm: /dev/md3 assembled from 2 drives - not enough to start the array.
    Has anyone any idea where did the two partitions go? I ran SMART-tests to all four drives in long mode and all of them passed the tests.
    I use GPT partitioning table, UEFI and Syslinux if it matters.

  • [SOLVED] Shudown panic with 3.5.5 and 3.5.6

    After upgrading to 3.5.5, my computer consistently crashes on each shutdown. The problem persists with latest 3.5.6. I have downgraded to 3.5.4 to restore clean shutdowns. This picture shows a crash in kworker, but even syslog-ng may crash:
        http://i.imgur.com/cZHZI.jpg (290 kb, screen shot)
    PS: I googled the recent days for shutdown crashes, but seems that I'm the only one. Anyone else?
    PS: I'm old, but this was my first screen... I apologize for having previously embedded the full picture!

    Starting with systemd my system no longer crashes at shutdown (!?). Tested with 3.6.2 (which also crashed at shutdown if I do the traditional boot, since I still haven't migrated to systemd).
    So, it seems that "traditional boot" is no longer stable at shutdown.
    Anyway, 3.6.2 heats my CPU to 70ºC (with previous kernels less than 50) and spins my fan a lot. I'll downgrade to 3.5.6, since the old kernel parameters to reduce fix power problems seem not to work either.

  • Need Sound Card Compatible With Intel D975XBX Mobo and Windows 7

    Did a search and no joy. I built a home theater computer about 5 years ago around the D975XBX,? I was using the Sigmatel integrated sound via toslink to my receiver without any problems. I installed W7 yesterday only to find that there are no Intel mobo drivers for W7. So before I go throught he hassle and expense of replacing the mobo and processor, are there any sound cards that are compatible with this mobo and W7? I don't do gaming on this machine, or 3D, mainly 5. out to my receiver. Thanks.
    Tim?

    DWell, I'll answer my own question. Finding it very hard to belei've that a driver wasn't available for the Sigmatel, I upgraded the Bios, then did another seach. Cha-ching, money!
    I really like SB cards, but I don't like spending money when I don't have to.
    Even though Intel said it stopped supporting?the mono?in '08, the bios was an '09 version. This may be helpful to others who are using this mobo.

  • [SOLVED] Choppy sound with Intel audio card

    Ever since I bought this laptop and installed Arch, I have experienced this annoying choppiness.
    What happens is that when I highlight other windows, under the minimum memory/cpu load the sound is truncated. I can't listen to music pleasantly on my laptop, and I can't stand it.
    My laptop is a HP 530, with an integrated Intel audio card. This is the output from hwd -s:
    Sound(a) : 82801G ICH7 Family High Definition Audio Controller module: snd-hda-intel
    I have 1Gb of RAM, and the processor doesn't seem very busy when the sound is truncated. This happens under any DE/WM - even in tty!
    For what is worth, I had problems with the speakers not muting when the headphones were plugged in, and I have followed the method indicated here.
    Thanks for your time.

    Auto is the default, it might not be resolving the model correctly (that's the case with my laptop).  Try model=hp.
    If that doesn't work, you could try turning off power saving:
    options snd-hda-intel power_save=0
