New install hangs on boot when GDM or LXDM services are enabled

Greetings Arch users,
I've been trying out installing Arch on a USB drive in order to get familiar with the process and use it on my main machine in the future. I've been following the Beginners' Guide, and after a few hiccups, I managed to install what appears to be a fully-functional Arch system onto a 16 GB USB drive, albeit without a window manager or desktop environment.
When I tried that is where I ran into problems. I installed X, vesa driver, and GNOME and enabled gdm.service, and upon the next reboot the system hung after or in the middle of the fsck process, exactly as described in this thread.
rebooted, hangs after the fsck bit where it says something like /dev/sda4: clean, 112977/9296096 files, 185427/21217024 blocks
I just get the blinking cursor. I left it there long enough to take a nap and nothing else came up.
Examining the journalctl output, I see an error exactly like mentioned in this thread:
GLib-GObject-CRITICAL: g_object_ref: assertion 'object->refcount > 0' failed
GLib-GObject-CRITICAL: g_object_unref: assertion 'object->refcount > 0' failed
Chrooting into the system and disabling gdm.service allowed for normal boot.
Well, I thought, maybe there's an issue with GDM or GNOME. I'll try LXDE and LXDM instead. Unfortunately, that hung at the exact same point in the loading process. Looking at the journalctl, I saw an output exactly like what was described in this thread:
Lxdm.service main process exited code=exited status=1/FAILURE
lxdm.service entered failed state
I'm stumped. I've searched and haven't come up with anything. Does anyone have any ideas about what might be the cause? What additional information would be helpful in diagnosing the issue? Thank you for your help.

GDM then restarts immediately. Problem recurring each boot.
Can you check the logs (dmesg, journalctl, xorg) and see if there are any differences for the startup of GDM before and after a successful GDM start.
Technically from the lack of information you provided it's not possible to state if you actually have the same issue or not. It might be better for you to start your own separate thread.
If you start your separate thread please provide some more details so people don't need to start guessing.
I think I'll just RTM.

New install, hangs at "GRUB Loading ..."

I just finished installing Arch on a new system, following the beginners guide, and everything went fine, until I restarted the system.
It shows "GRUB Loading ...", and a blinking cursor, and nothing else. The GRUB menu never comes up.
Has anyone encountered this before?
I'd say I have a fairly simple setup:
/boot /dev/sda1 ext2 300MB
/ ext4 /dev/sda2 120GB
I made the partitions with fdisk, so I have the "old" MBR partition table.
I have installed grub with:
(boot the install medium)
loadkeys hu
mount /dev/sda2 /mnt
mount /dev/sda1 /mnt/boot
arch-chroot /mnt
pacman -S grub-bios
grub-install --target=i386-pc --recheck /dev/sda
(Grub install finishes, says no errors detected)
cp /usr/share/locale/en\@quot/LC_MESSAGES/grub.mo /boot/grub/locale/en.mo
grub-mkconfig -o /boot/grub/grub.cfg
exit
umount /mnt/boot
umount /mnt
reboot
And then I'm back to the hanging BIOS Loading screen.
Edit:
There were some pieces of information regarding an encrypt root drive, I have retried the install without encrypting the root drive, and the problem perists.
Edit2:
Syslinux boots it just fine.

Yes, 2 MiB if GPT is used. That's what I meant. And don't use "/dev/sda1" or "/dev/sda2" when installing GRUB. You want to install to the MBR, so use /dev/sda.
https://wiki.archlinux.org/index.php/Be … bootloader
Also: https://wiki.archlinux.org/index.php/Be … partitions
Pay attention, because the mounting order is important.
First, mount the root partition on /mnt.
Then mount the /home partition and any other separate partition (/boot, /var, etc), if you have any.
So do not mount the boot partition first, then the root partition after. That's just wrong.
You mentioned encryption earlier. Well? Which is it? Encrypted or not? Because you can't just mount it like any regular partition if it's encrypted.
If you still want to go with Syslinux, see the Basic Config for encryption examples.

[SOLVED] New installation hangs on boot at two different places

Hello
I recently made my another attempt at installing arch on a new desktop build. Previous successful attempts were old laptops.
I followed the Beginner's Guide on the Arch wiki.
Currently it stops at one of two places in the boot process:
1. [ OK ] Found device Samsung_SSD_850_EVO_500GB BOOTARCH
Starting File System Check on /dev/sdb6…
2. [ OK ] Started Journal Service
[ OK ] Started udev Kernel Device Manager
I can not consistently recreate either scenario, but it seems to be random which of the two places it stops. Cold boot and CTRL ALT Delete. I doubt that has anything to do with it, but thought I'd add it anyway.
Current setup:
Hardware:
Motherboard - ASUS Z97 Pro (using ethernet adapter and sound on here)
Processor - Intel 4790K
Memory - 16 GB
Graphics - Gigabyte G1 Nvidia GTX 970 SLI x2
Storage - Samsung 850 SSD 500 GB and WD Black HDD 3 TB
I've also configured it to use a static IP
I started this journey by using the live Gparted CD to create partitions. I created two partitions on the SSD. One for windows 8.1 and one for linux. I then created two partitions on the HDD. One for windows, one for linux.
I installed windows 8.1 first. It divided up the partition I gave it. I am able to run Windows. Once that was done I began installing Arch.
I used the Feb 2015 ISO from the torrent.
Current partition scheme for linux:
sda1 /home
sda3 /swap
sda4 /var
sdb1 /
sdb6 /boot
sda is the HDD and sdb is the SSD
The other partitions not listed are for windows. To boot into windows, I use F8 to choose the windows boot manager partition. It currently defaults to the linux partition.
During the install, I mounted the root partition first. I then created directories for each of the other partitions and then mounted them. Home, var, and root are all ext4. Boot is FAT32, and Swap is swap.
I read where I made a couple of mistakes the first attempt on this computer and did a wipe and reinstall again. First mistake was not knowing that /boot needed to be FAT. I then learned that /swap does not need to be in the fstab. I also learned that a FAT partition can not use UUID in the fstab so I took that out and just used /dev/sdb6 instead.
I have run out of things to search for at this point and need help to continue moving forward.
Bellow is the current /etc/fstab. It was generated using
genfstab -U -p /mnt >> /mnt/etc/fstab
and then edited as noted above
#/dev/sdb1 LABEL=archroot
UUID=xxxxxxxxxxxxxxx / ext4 rw,relatime,data=ordered 0 1
#/dev/sdb6 LABEL=BOOTARCH
#UUID=xxxxxxxxx
/dev/sdb6 /boot vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro 0 2
# /dev/sda1 LABEL=linux\134x20home
UUID=xxxxxxxx /home ext4 rw,relatime,data=ordered 0 2
#/dev/sda4 LABEL=archvar
UUID=xxxxxxxxxx /var ext4 rw,relatime,data=ordered 0 2
#/dev/sda3
#UUID=xxxxxxxxxxxxxx none swap defaults 0 0
Thanks for any help that can be provided

I tried removing gummiboot and installed GRUB2. That didn't work.
As to the UUID's, I just typed in xxxxx's for the post because I didn't feel like transcribing random letters and numbers.
So after reading Head_on_a_Stick's suggestion, I redid my partitions and reinstalled arch again following the Beginner's wiki page and using gummiboot
New Partitions are as follows:
sda1 /home
sda3 /swap
sda4 /var
sdb1 /
sdb3 /boot (originally created from windows install)
Also, I took a screenshot from Gparted of the two disks if there is any info on there that may be of use

New Install Won't boot after GRUB

I have been using ArchBang for the past year and a half so I finally thought that I knew enough about Linux to try installing a true Arch Linux system.
I followed the beginner instructions carefully and was able to successfully install my system (or at least I thought) and GRUB. I am currently running my system on a Dell inspiron with two separate hard drives. The primary drive is the one I am trying to install Arch on while I have Windows 7 installed on the second drive.
The drive I installed Arch on is /dev/sde. I think that I successfully installed GRUB given that when I boot my computer it goes into GRUB and shows both my Arch Linux install and my Windows 7 system and when I select Windows 7 in GRUB it successfully boots.
But when I selected my Arch install in GRUB the system does not boot. It just shows:
/dev/sda1: clean, 31087/3751936 files, 478966/15000685 blocks
and then I am left with a blinking cursor and after a few minutes I get:
Welcome to emergency mode. Use "systemctl default" or ^D to enter default mode.
Give root password for maintance:
Anyone one how I fix this? Do I need to reinstall? As I said before I didn't receive any errors during the install and GRUB seems to be working correctly. Please remember that I am a newbie but please help!

No you don't need to reinstall, you do need to fix your grub configuration though. It sounds like it is not properly pointing to the root partition.
Post your grub config and your partitioning scheme.

I don't now if this output of the partition table is what you want given that the lsblk is the only command I am familiar with. The sdb disk is where the windows install is.

What are the ports required for the Audio, Video and A/V conferencing when the following end points are enabled for QoS in Lync 2013 server?

Hi All,
What are the ports required for the Audio, Video and A/V conferencing when the following clients are enabled for QoS in Lync 2013 server?
Client Type
Port range and Protocol required for Audio
Port range and Protocol required for
Video
Port range and Protocol required for
A/Vconferencing
Windows Desktop Client
Windows mobile App
Iphone
Ipad
Andriod phone
Andriod Tablet
MAC desktop client
Please advise. Many Thanks.

Out of the box, 1024-65535 for all of the client ports. :)
https://technet.microsoft.com/en-us/library/gg398833.aspx
You'll want to tune your client ports a bit
https://technet.microsoft.com/en-us/library/jj204760.aspx as seen here, and then the client ports would use those ranges which is easier to set QoS markings. I'm not sure the mobile clients respect that setting.
Elan's got the best writeup for Windows clients here:
http://www.shudnow.net/2013/02/16/enabling-qos-for-lync-server-2013-and-various-clients-part-1/
However, the marking of the packets is the tricky part. Windows can do it via Group Policy, but for the other clients you'll need to have the network specifically prioritize ports regardless of DSCP markings. You have to do it based on ports
as the traffic could be peer to peer.

[Solved/Broken DPM] Hang at boot when switching modes with radeon

When I tried to boot into Arch about a week ago after cleaning some dust out of my case I was met with a nasty surprise, it wouldn't boot properly! Once my system got to the point where it would usually change resolutions (KMS kicks in) my displays (1 DVI, 1 DVI -> VGA) would just shut off (presumably not getting any signal from my GPU a Radeon 5770) and either my keyboards lights (caps/scroll/num) would either be stuck on or be able to be toggled but I don't believe anything was happening in the boot process.
Now me being the inquisitive kind of guy I decided I would be right on the case and ignore Arch until I got bored. I tried out an old Ubuntu 12.04 based distro and everything worked fine, but that's no way to live so I decided to install Debian testing. The install went fine, everything was happy, and I even made it to a tty! But during the boot I noticed a message saying I didn't have the non-free firmware I'd need for my GPU, so I installed that and rebooted.
Much to my pleasure the same issue didn't happen! Instead of only (presumably) locking up my GPU fans were going very fast and loud blowing a bit of extra dust out of my case for me. How convenient! At this point I decided the problem was probably the fault of the firmware, but why did it just start happening now? Perhaps I updated my system before I opened it up; I don't remember if that is the case or not however.
Anyways, Debian testing was a bust so I decided I'd reinstall Arch, so I booted up my trusty flash drive and.... the same thing happened. While I considered the possibility of hardware failure, Windows works the same as it always has and the old distro didn't have any issues aside from generally being old and terrible and my computer is yet to catch on fire. I also ran a small memory test to make sure everything seemed normal enough.
tl;dr Boot fails when KMS initiates (?) / Hardware seems fine / Maybe a problem with new kernel or firmware
Anyone else have issues or a solution?
EDIT: Disabling DPM fixed my issues, but of course I don't have dpm now

You can try building the kernel from git. There is an AUR package.
Or try the drm-fixes-3.16 branch from git://people.freedesktop.org/~agd5f/linux (http://cgit.freedesktop.org/~agd5f/linux/)
For me (HD6870) it fixes the power management. But i had other symptoms: https://bugzilla.kernel.org/show_bug.cgi?id=68571

[SOLVED] new install hangs at fsck

Hi all,
I am trying my first install on the new installation media 10-6. Everything seemed to go smoothly until I rebooted. Now boot hangs at Filesystem is clean. The full message I am stuck on is below.

I ran into something similar yesterday.. I'm not sure it's the same problem but here's what I tried and found.
*After an unsucessful boot, restart your computer and boot off the installation media
*Mount your paritions on /mnt as you would for a fresh install.
*Run arch-chroot /mnt to chroot into your installation.
*Now you can run journalctl to see all messages logged during boot. There will be a ton of them, so hit 'G' to scroll to the bottom.
*Look for messages in red or white.
Now, in my case I found some errors from nouveau and dri. After those errors, the logs went on to show that the system fully booted, although I never got past the fsck step on the screen. A bit of searching found posts about problems with nouveau and dual graphics cards (I have on-board GPU + a Nvidia card). Some posts mentioned adding the nomodeset option to your kernel line in grub. Doing this allowed me to boot up, and after installing the nvidia driver, I was able to remove this option and still boot.
Hope this helps.
Edit: grub config with nomodeset
echo 'Loading Linux core repo kernel ...'

10.3 Server new install won't boot from Mirrored RAID - HELP!!

Hi all,
I had 10.3 Server running fine on a 450 MHz B&W G3 (home server use, nothing too demanding), when I decided to add a 2nd HD and run the server from a RAID mirror (both 80GB drives). I had problems enabling RAID on the boot drive with diskutil in Terminal, so I decided to rebuild the server. I didn't have much besides the system on it, so backing up data and re-installing isn't a big ordeal (or so I thought).
No problems creating the mirror set once I re-formatted the drives. The install seemed to go fine (10.3.4 on install disk), but upon restart, I got the flashing system folder/question mark. When booting from the install disk, Disk Utility recognizes the RAID, and Startup Disk recognizes the mirror as a viable boot drive and allows me to select it and restart. Same problem, no system found.
When I run diskutil info for the mirror, it lists the mirror volume as Not Bootable.
I've checked the disks with both Disk Utility and DiskWarrior - all looks OK. I've reset PRAM and NVRAM, taken out added PCI cards, and disconnected all FW and USB devices (besides kbd and mouse).
Unfortunately, B&W G3 can't boot from an external FW drive, so I'm stuck with booting from a CD/DVD for troubleshooting.
My next step is to re-install on a single drive again and try to enable RAID and mirror, but I'd sure like to avoid that if I could.
I've searched through this board and didn't really see this particular situation. Any of you smart server folks seen this before -- any ideas or suggestions??
TIA,
Brad

if you backup your data from a NON-RAID Drive (Single drive), create a RAID array and then Restore from the backup you created... you will find you cannot boot from the drive.
Apparently the sector or drive header information in a non-RAID drive is different than in a RAID array... so when you restore the backup data from the non-RAID drive to the new RAID Array; you effectively corrupt the RAID array not allowing it to be booted from.
The solution is to create the RAID array and then re-install your system from scratch... copying over the data you want to keep from your initial backup one file at a time (don't do a complete system copy or you will once again, corrupt your new RAID install).
I had the same problem and it took me a great deal of time to figure it out.

Dad needs Help, 180 New Install- Hang on Verify Pool DMI

Trying to build a new system with my son, he has put it together (with supervision) and I can't get the SW to load.... So not looking too good right now...
Bought a Mega 180

Sony DRU-540 DCD+-RW/+-RCD Drive
Corsair 512Mb (2 DDR-Dims)
Assembled the machine. Went smoothly, needed to reseat ram simms once. Got the system to boot to bios. Windows xp pro failed to install. Friend had a set of dev discs and had a made me a copy and given me one of his licenses. Install had started and hung on loading before being asked for serial number.
On reboot system hangs in bios screen with
Verify DMI Pool ....
What to i do next? thx in advance

I would suspect you have another computer. If so download the lastest BIOS for it from the Msi web site. Then useing a USB key or connecting a floppy drive then flash it in DOS.
The floppy connecter is on the mother board just no cable, also by default the floppy drive is turned off in BIOS so you will need to enable it.
If you are going to use a floppy disc to reprogram then do a full disc scan on the disc with the drive you will be using, the last thing you want is to have a bad disc. If you do have a bad disc and you only find out during flashing then keep that machine turn on and with you other PC load the BIOS on another disc and try again (don't turn it off).

New install won't boot

I got a new laptop a couple of days ago and wanted to install Arch on it. Everything went fine until I tried booting it. I'm not sure where it gets stuck but I believe it's at the step where it waits for UDev uevents to be processed. Why I believe this is, is because that's also the point where it takes a fairly long while to get past when booting the install CD.
I took some pictures and a video of my laptop trying to boot into Arch which you can find here: http://yuri.vm.madoka.be/arch/
The first picture is where it gets stuck when booting normally, the next pictures are taken when booting from the CD.
If anyone could help me it'd be greatly appreciated.

JokerBoy wrote:adding nomodeset to the kernel boot line helps?
That one worked. Before this I also tried blacklisting nouveau by booting System Rescue CD. On that CD I also noticed I couldn't boot into a graphical environment so is it nouveau not playing nicely with my hardware or my hardware acting up? (New laptop...)
I also just tried installing the official NVidia driver and so far I have successfully started an X server which seems to work perfectly.
So basically I'm just wondering if there's a way to get Nouveau working in case I need it. I'll be using the official drivers when using Arch but if I ever need a GUI on my System Rescue CD I'm pretty much f'ed at the moment...

[PPC] new install fails to boot: root partition not found

Hi,
new ArchPPC installation on a iMac G3. It does not boot further than initramfs because root partition is not found. I get something like:
Root device /dev/sda4 doesn't exist
Attempting to created it
ERROR: unable to determine major/minor number of root device /dev/sda4
then I get a dropbox recovery console but keyboard doesn't work.
I chroot in the installed system to change mkinicpio pata hook to ide, regenerated initramfs but that didn't help.
Any guidance to diagnose and solve this issue would be greatly appreciated.

Hi, sorry I just realized you replied to my thread.
I don't have my mac at the moment, but I must have done something like :
- boot the live CD
- get the output of lsmod
- copy this output to mkinitcpio.conf (the one that's on your HD), remove the autodetect hook
- chroot into your HD setup
- regenerate initramfs
- update yaboot (is this really mandatory?)
- exit chroot and reboot.

QuickTime new install hangs, freezes executing MOV files?

Once worked?
A iTunes user I have removed & reinstalled ITunes back having same issue never fixed awhile (I did not know it was I QuickTime thing)
I tried to run any video in iTunes or podcast and it freezed.. I lost mouse keybd everything Reboot!
That was iTunes on another ticket suggested that I remove & reinstalled... same problem, never did solve it?
Today I tried QT, running a MOV from fresh boot, to execute a MOV file, one that worked and I created a year ago..
I went repair soft and apps in control panel, then finally remove & reloaded it, Quicktime still freezes when executing a MOV file.

1] Try it with another user account (make one if you need to in Apple menu > System Preferences > Accounts)
2] If its only happening in your account:
Inside your hard drive, in the Users folder should be your user home folder (with your account name.) Within that folder is a folder called Library... open that and look for a QuickTime folder within, pull that QuickTime folder out to the Desktop. Do the same for Internet Plug-ins and throw away the ~/Library/Caches/QuickTime folder too. Then, open Preferences and pull out com.apple.quicktime... (all of them) and the QuickTime Preferences file.
Then log out (Apple menu) and back in (or restart) and try again.
3] If its happening for all users then try:
Pull the /Library/Preferences/com.apple.quicktime.plist to the desktop (Your QuickTime Pro registration is in that file so don't throw it away, just move it out, restart and try again.)
4] If there are still problems, try repairing your disk either with the OS X install disc (run Disk Utility from the menu bar) or by rebooting in Singel-User-Mode and running fsck. Then repair permissions with Disk Utility.
Let us know if you still have trouble.

W520 hangs on boot when a WD SES USB drive is connected

Hi,
Computer: W520
Hard drive: Western Digital - My Passport (SES Drive - encrypted)
When I boot with the usb hard drive connected to any usb port on the computer, the computer hangs forever at boot time. If I unplug the drive and reboot, everything is fine. I was able to fix the problem by disabling the USB support in the bios but then, none of the USB ports work in Windows.
I believe this is due to the SES function of the WD usb hard drive (see: http://wdc.custhelp.com/app/answers/detail/a_id/3701/~/computer-freezes-when-it-restarts-with-a-wd-m...
Also, a previous post with a similar problem was written on this board but provided no working solution (see: http://forums.lenovo.com/t5/W-Series-ThinkPad-Laptops/W520-won-t-boot-with-SES-device-connected-to-U...
Thanks in advance for your help.

Hello jeantremblay44,
As I understand the laptop cannot boot if the external USB drive is connected.
Kindly try the following troubleshooting step
You can make the USB boot disable from BIOS and make the first boot device as Hard Disk
Best Regards,
Tanuj

Mountain Lion Hangs on Boot when an external cloned drive is attached

It seems that, for me at least, when I have an external drive, in this case a usb, plugged in on boot up, Mountain Lion just hangs. This external drive is used as a clone (I use Super Duper). It can hang in one of 2 places; after inputing my password, or when trying to bring up the desktop. It is very consistent as to the hanging. When the external drive which contains the clone is not attached, it boots fine every time. I have no problems at all with my other external drives being plugged in at boot. They are just contain data. Is Mountain Lion getting confused? Anyone else experience this?

I am stumped too. The issue is that the 'pmset -g' command does not allow changing the ExternalMedia flag.
An observation that may be relevant to this topic is as follows: if you unmount the drive (but not physically disconnect it), sleep comes in the specified time. Upon wakeup, however, the drive is mounted again to the desktop. I've noticed this behavior with SD cards, and I assume that HDs should do the same.
If this is the case, then it may be possible to use ControlPlane (current version is ControlPlane-1.1.4) and create an "about to sleep" situation, which triggers USB disk unmounting. Haven't tried it, but was thinking to (subsequently just gave up and eject my USB storage manually).
Hope this helps.
