Cannot connect to X server after resume from suspend

Hello,
i'm a happy user of arch and i3, one and only thing that is not working correctly is that sometimes after resume from sleep (closing the lid, and then opening) I am not able to start any programs. this happens about 50% of the time. when it happens i have to exit i3 and login again, and everything works ok then.
I'd be grateful for any suggestion how can I debug and solve this problem.

the error was, after running xterm:
No protocol specified
xterm: Xt error: Can't open display: :0.0
after running scrot
No protocol specified
giblib error: Can't open X display. It *is* running, yeah?
after running firefox
(process:2559): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed
No protocol specified
No protocol specified
Error: cannot open display: :0.0
but I think I was able to fix the problem.
when I was browsing the internet for solution, I stumbled upon an info about similar problem caused by the hostname set to localhost. I checked my system, and apparently I haven't set my host name during install, and it was still localhost, so I changed it. and after that I tried suspending several times, and the problem never occured. I'll test in upcoming days, and if it works I will change the thread title to [SOLVED].

System freeze after resume from suspend

I am running arch for about 5 month now and I always had freezes after resuming from suspend (to ram - systemctl suspend) every once in a while (like once a week or less). The freezes increased massively over the last month or so and for about 2 weeks now it happens 95% of the times I resume from suspend.
The monitor turns on and shows things exactly how I left them, but is completely unresponsible EXCEPT for I can switch to another TTY (Ctrl+Shift+F*), however I cannot type or do anything in it...
It doesnt have anything to do with the X server as it also happens after I suspend from TTY (without any X running).
I also checked journalctl -b -1 (shows previous boot, since I always have to hard-reset the system) but it doesnt show anything after:
Mar 13 17:16:54 Ununhaswellium systemd-sleep[3624]: Suspending system...
(the suspend event before resuming)
Are there any log files that could give a hint on what exactly goes on after the resume?
Im running the latest official 3.13.6-1 kernel and updated my BIOS to the latest beta version yesterday - didnt help either...
Ive read pretty much every thread on the internet by now about freezes after resume from suspend but none really helped

And other than in this bug report I cannot kill X or anything because neither other TTYs work - I cannot input anything (although the hotkeys work weird enough) nor is SSHD running because the system is completely frozen...
Very funny thing is that for the last 2 days my system didnt freeze once (suspended about 6-7 times during one boot), even though for the 2 weeks prior to that, it froze EVERY SINGLE TIME I resumed from suspend, it didnt work once...

Touchpad permanently not working after resuming from suspend

I lost touchpad and trackpoint functionality after resuming from suspend on my ThinkPad E530 (3259CTO).
Even after a complete power off (with the battery removed), the touchpad is detected but doesn't send any event, and the trackpoint is not detected.
In Windows, in the UltraNav control panel, the touchpad is marked as enabled and cannot be disabled, the trackpoint is grayed.
In Linux, I can see the difference is kernel traces when the driver is loaded.
Before : psmouse serio1: synaptics: Touchpad model: 1, fw: 8.0, id: 0x1e2b1, caps: 0xd001a3/0x940300/0x120c00
Now : psmouse serio1: synaptics: Touchpad model: 1, fw: 8.0, id: 0x1e2b1, caps: 0xd001a3/0x0/0x0
After looking at https://gerrit.chromium.org/gerrit/#/c/31105/ and Synaptics public documentation, I was able to get more information : the device status register (F01_RMI_Data0) is 0x45, which means the touchpad is in flash programming mode since there is a firmware CRC failure.
It looks like http://code.google.com/p/chromium-os/issues/detail?id=24298, so it's probably not a Lenovo specific problem, but a bug in Synaptics firmware.
Can Lenovo provide the firmware to flash like http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/X220-Touchpad-jumpy-response-when-used-with-90... which would hopefully make my touchpad working again ?
The original firmware should work, but an updated one would be better, if it avoids losing the touchpad again later.

I don't know why, but this made me think of the episode of the simpsons when home tries to get over 300 pounds so he can work from home. When he tries to dial the phone he hist all the buttons and gets a recording that says "We're sorry, you're fingers are too fat. To obtain a special dialing wand, please mash the keypad now."
BTW, sorry I can't help... but at least I am entertained easily.

No sound in Flash after resuming from suspend

After I resume from a suspend or sleep there is no sound in Flash and there is no networking.
The only way is to restart my browser to reestablish the sound.
Is there a solution for this problem?
Thanks.

This does not happen with Firefox in Ubuntu, as an example. So something must be wrong somewhere.
I can confirm this happens to me in Arch with Firefox 4.0b7 and Chromium 7.0.517.44. I noticed that after resuming from suspend, not only sound (in Flash) is missing, but Flash is behaving weirdly (YouTube video plays much faster) and CPU usage goes crazy without doing any particular action.

System freeze after resume from suspend to RAM

Hi,
since quite a while (probably ever) I am unable to suspend my computer to RAM because everytime it freezes a few seconds after resuming, never to become alive again until a reboot. After some investigation, I managed to get kernel logs by taking a picture of my screen. The logs were not written to disk, hence I didn't see anything before. I had to write these by hand, I hope I didn't insert any mistakes:

This issue seems to be related to disk failures like bad sectors but I am quite sure, that my SSDs are in a good shape. I ran some SMART tests, they all turned out to be okay. Suspending from my dual-booted Windows works fine as well (although if the bad sector would be on the linux partition, it would probably not affect Windows).
Here's my setup:

I am not sure which one of the disks causes the freeze but I assume it's the revodrive because the logs talk about two drives. The Revodrive internally holds two drives, which are set up to operate in a RAID 0. Windows is installed on the Corsair drive, and has no access to the Revodrive. However, I used to run Windows on the Revodrive a few years ago, and it worked just fine.
Another interesting thing is that when I try to test suspend to RAM, the system does not freeze, nor produce errors. This only happens if none is written to /sys/power/pm_test (which means no automated wake-up, no testing).
Any ideas on how I could narrow down this issue? Thanks a lot!
EDIT
I just checked and confirmed that this issue is originating from the OCZ Revodrive:

Dell Inspiron 7537 - Sound only works after resuming from suspend

Hello,
So my sound does not work after boot, only once I resume from suspend. So, once I turn on my computer, and I load sound, nothing work (everything is unmuted in Alsa) - then if I suspend my computer and resume - the sound works every time.
I use Alsa and here is my amixer output (before and after suspend is the same) :
eric@archlinux ~> amixer
Simple mixer control 'Master',0
Capabilities: pvolume pswitch pswitch-joined
Playback channels: Front Left - Front Right

What gets rebooted when I do a suspend, but not when I reboot? Does not seem to make sense to me.
Thanks.

Is there any additional information I can include to help figure this out?

Desktop visible after resume (from suspend) and before screen is locke

My desktop becomes visible for brief period (<1s) when the system resumes from suspended state. My desktop env. is XFCE4, it happens with both xscreensaver and gnome-screensaver (also with slimlock and i3lock), therefore I think it's not locker dependent. It's a major security flaw because sensitive information may be exposed (not just porn). Using both XFCE provided locking facilities (suspend/resume lock options in Power Manager and Session settings), and systemd suspend/resume hooks yields same result. I remember back then when I was using Gnome, I haven't had this issues. Does anyone have any idea how to prevent this desktop expose?

Have you tried this --> https://wiki.archlinux.org/index.php/Pm … or_suspend ?

No sound in flash after resume from suspend (linux debian)

Using 10.0.r42, iceweael and linux 2.6.32 kernel.
If I close the lid on my HP laptop which causes it to suspend, and the resume from suspend, other audio playing programs work, but I cant get any sound from iceweasel/flash until I kill all instances of iceweasel and restart the web browser.
Is this a bug that is tied to flash?

What a coincidence, mine is also from scratch.
Good question about how sound is handled. ldd libflashplayer.so doen't give an answer.
So somehow xulrunner can catch the sound.
Libxpcom is linked to libasound. components/libmozgnome.so to libesd in my case.
Maybe you can try fuser /dev/snd/* to identify which process is locking the device.

Lync client cannot connect to Exchange Server when accessing from outside (Internet) - please HELP!

Hello,
I have full representation of the Lync 2010 from Outside (i.e. Internet), but I still have small issue related to Lync-to-Exchange integration. Clients who is using Lync client from outside (i.e. Internet) cannot see Exchange-related information including
Call Logs, Voicemail and Calendar information.
Here is the experience and error messages that anyone will see when connecting to Lync server from Outside:
And this is the error message that will be displayed on Lync phone edition devices (a.g. Polycom CX-700) when connected from Internet:
If somebody can suggest what I can try I would appreciate this very much. I do believe that many other people have this issue as well.
Thanks!

Hi, we had this issue and I ended up logging a MS support job. Turns out it was the TMG rule/Auth method causing the issue.
Job details:
**Symptom:
Lync Client External User are not able to retrieve the EWS URL
**Troubleshooting:
• We found External users are not able to Retrieve the EWS information in the Lync Client .
• We found the below error in the ETL logs.We found for EWS request we are getting the 401 response
HTTP/1.1 401 Unauthorized ( The server requires authorization to fulfill the request. Access to the Web server is denied. Contact the server administrator. )
• TMG need pass through Authentication
Public names are autodiscover.domain.com and Outlook anywhere External FQDN and paths are /ews/* and /autodiscover/*, OAB/*
Users is All Users, and Delegation is "No delegation but client may authenticate directly" on the corresponding tabs of the publishing rule.
This changes is required for Lync Client as Lync Client does not work well with this BASIC authentication on TMG .
• After TMG engineer changed this settings in the TMG users are able to see EWS information.

at this point I am assume that the issue is related to security. I am able to query the database as admin from the effected servers and other services that use other databases in the same sql instance are no5 having issues.
I have checked the security group that both cb servers should be in and they are in the group and the group has sysadmin and dbo within sql
any ideas?

Similarly, running 'sudo systemctl restart NetworkManager' doens't help as I only get a wifi connection. Journal messages are pretty much the same as above. I'm trying to determine if this is a driver issue, but I don't see anything relevant in the journal. I've seen a couple of bugs on the Debian bug tracker https://bugs.debian.org/cgi-bin/bugrepo … bug=743206. That one appears to be solved as " network-manager 0.9.8.8-6". I currently have 0.9.10.0-1.
Interestingly, sometimes when I try and restart networkmanager from gnome's menu, I see
dhcpcd[8545]: dhcpcd already running on pid 8330 (/run/dhcpcd-enp2s0.pid)
After running 'sudo systemctl stop NetworkManager' followed by 'sudo killall dhcpcd' and 'sudo systemctl start NetworkManager' I get wifi but no wired connection. Anybody have any ideas?
EDIT: Any suspicions against dhcpcd are unfounded as behavior using dhclient is not much better. After wake-up I apparently do have a wired connection, but pings to 8.8.8.8 and www.google.com both fail. Restart networkmanager using systemctl does not work as with dhcpcd. Stopping networkmanager, killing all dhclient processes and restarting networkmanager do restore my connection to the internet though. Sorry for my scatterbrained attempt at troubleshooting this. My difficulty here is pinpointing an exact sequence of steps that results in consistent behavior. So far, after waking from sleep any of my above attempts at getting a network connection have varying degrees of success and failure.

As the title states, I'm having trouble getting a wired connection after suspend on my laptop. For reference, here is my card (using the r8168 driver):
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06)
This is relevant journalctl output after wake-up:

Firefox cannot open/reload any websites after resuming from a system standby. I have to close the current window and start a new session, then it works again

I am using Firefox v 13.0.1 (Mozilla Firefox for Ubuntu canonical 1.0) on Ubuntu 12.04 LTS. Whenever my system resumes from standby I am not able to open/load any webpages in the Firefox session that was already running before the standby. I don't get any error message, but the page doesn't load at all. If I close the session and start a new one everything works fine.

Not necessarily: rv:1.9.2.8 indicates a Firefox 3.6.8 version
*Mozilla/5.0 (X11; Linux i686; rv:1.9.2.8) Gecko/20100722 Firefox/4.0.1
You can check for a possibly corrupted user agent.
