Debian Hardware :: Wheezy No Longer Recognises Monitor After Reboot

Sep 11, 2014

I have installed no updates and made no changes to configuration in any way. Computer has been left on for some time. Finally rebooted to clear any caches. When it came up again the system does not recognise the monitor. So I get the default resolution. Not hardware as a windows install comes up fine.

Using Wheezy with MATE
Running on Haswell
Installed backport to stop crash on exit 3.13-0.bpo.1-amd64

I have tried several versions of live CD. These all give the same symptom - which is why I tried the windows install. So I suspect this is something to do with recognising the onboard graphics in Haswell.

I have googled and found, however, means using a shell script. This seems rather drastic and I don't want to go that way unless there is no other possiblity of a solution. In that post the output of xrandr is posted so doing the same here.

Code: Select all xrandr -q --verbose
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1600 x 1200, current 1600 x 1200, maximum 1600 x 1200
default connected 1600x1200+0+0 (0x138) normal (normal) 0mm x 0mm
   Identifier: 0x137
   Timestamp:  4622
   Subpixel:   unknown

[Code] ....

Resolution : Linux system does not like both DVI and VGA cable plugged in at the same time.

Debian Configuration :: Samba Share No Longer Auto-mounting In Wheezy

May 1, 2011

I upgraded my testing/Wheezy Inspiron N5010 to 2.6.38-2-amd64 recently (along with a bunch of other updates, of course) and now my Samba network share is no longer automatically mounting, I have to open a root terminal and do a "mount /mountpoint"; my relevant /etc/fstab entry:

I've tried over options, as well, but it isn't automatically mounting. Any suggestions (including where to file a bug report)?

Debian Hardware :: Android Phone No Longer Mounting Since Wheezy -> Jessie

Aug 7, 2015

Used to be, when I connected my phone and turned on USB Storage, it would automount, and I'd get a popup window asking me what I wanted to do (open and view files, or import photos with gthumb). I would just choose open and view files, move photos, music, etc. back and forth...

I would see the device listed in pcmanfm or thunar. Now, nothing happens. I do not get the popup, nor see the device in any file manager, etc. When I do fdisk -l, I do not see the phone listed, but when I do lsusb, I do see it.

Code: Select allBus 008 Device 067: ID 0482:0734 Kyocera Corp.
Bus 008 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

It's a Kyocera Hydro Elite, an android device, set for USB Mass Storage upon connection. The phone knows when it's been connected and gives me the option to turn on the mass storage, which used to trigger the popup on the computer, but the computer no longer responds.

I have thunar-volman and mtp-tools installed.

I don't seem to have any relevant entry in /etc/fstab. Not sure if I did before upgrading to jessie from wheezy or not... I don't believe so...don't think an upgrade would wipe anything from there.

Why I'm not getting access to the phone now? Or how I can mount it without knowing it's location from fdisk? I do not use gnome, but rather plain openbox.

Debian Hardware :: Reboot / Restart Instead Of Shutdown (wheezy)

Oct 16, 2012

Come across with a situation where all methods of shutdown result in a restart/reboot? I've tried commands:

- shutdown
- halt
- poweroff

.. with various parameters, nothing works. The laptop seems to power off, but after a sec it restarts/reboots. I've Googled high and low, but there's very little on this topic. Maybe it is specific to the current kernel in Wheezy? I'm not suspecting a harware failure, since this was not happening with Windows installed.

This happens on me with Wheezy on a HP Elitebook 8530w.

Debian :: Dedi Server Don't Reboot After Wheezy / Jessie Upgrade

Jul 26, 2015

I have upgraded my debian server on april when Jessie came up, but I *forgot* to reboot at this time. As a new kernel* was released this week as a security update, and since my server installed it (via unattended-upgrade on security packages), I rebooted it last night. It never came back online.

I have access to a rescue boot (Ubuntu 12.04 LTS), and tried to analyse the failure (by mounting /sys /dev /proc and /boot and chrooting), but without luck so far.

As it's a dedicated server, I don't have access to the console. What I know :

No log in var/log since the failed reboot. I don't know how to have/find others logs.Previous kernel was 3.2.0-4-amd64, new is 3.16.0-4-amd64, What I tried without luck) :

Change the booting kernel, via update-grub. Tried 3.2, 3.2 with sysvinit and 3.16 rescue mode I think. I should have done it right, but without console it's hard to tell.apt-get update/apt-get upgrade/apt-get dist-upgradeadding nomodeset to kernel load in grubWhat I haven't tried :

update-initramfs, I don't really know why it would block the boot

*linux-image-3.16.0-4-amd64:amd64 3.16.7-ckt11-1+deb8u2

Debian Hardware :: Wheezy 7.8 With LXDE Desktop - Task Bar Volume Control No Longer Functions

Feb 11, 2015

Running Wheezy 7.8 with LXDE desktop. I have noticed that the task bar volume control no longer seems to function. Volume can be controlled by apps, such as Youtube in Google Chrome. The volume control used to work. I really don't know exactly when this started but probably after the last update on Monday, Feb. 10 2015.

I have checked the PulseAudio settings and don't see any way there. Ran a sound test and the volume can be controlled from the PulseAudio panel but NOT the task bar volume control.

Here is a bit of interesting additional info. When I play the audio thru my analog speakers the volume control has no affect. But when I play the sound thru my USB headset, the volume control works. Very strange.

* more or less solved. still not exactly what I want but it works, mostly.

Debian :: Monitor / Video Output Turned Off In Wheezy?

Apr 2, 2015

Fairly new to debian and linux and general. I have an install of debian wheezy (to run LinuxCNC). I went in the graphical interface to the 'monitor' section and changed the screen resolution. I had two monitors, one labeled monitor and another (I think) Lenovo Monitor.

There was a check box in the screen monitor window that said something like, "Don't use this display." I figured it might turn off the lenovo and default to the generic monitor listed. I clicked it and my monitor turned OFF!! I tried another monitor (Dell in this case) and same thing, no video output.

I asked on the LinuxCNC forum and googled, but I just dont' seem to be able to figure out what or how to get to the solution.

I have been able to Ctrl-Alt-F1 to open a terminal. But, I can't find any the right files and found that the xrandr command 'should' work, but doesn't.

Whenever I issued the xrandr command (other than man xrandr), I get "Can't Open Display"

I did find two outputs VGA1 and LVDS1 in this file /var/log/Xorg.0.log and this coincides with what I saw in the monitor window. These are the 'output' types and if the xrandr command worked I'd issue something like : xrandr --ouptut LVDS1 --auto

I read about xorg.conf, but I could not find any xorg.conf files in the etc/X11 folder. In some of the info I found, the xorg.conf was replaced in this or a recent version of Debian by something else and confuses me.

One person had a similar issue and he got to this directory: $HOME/.e/e/config/standard" and found files such as:
"e_randr.cfg" plus "e_randr.1.cfg" thru "e_randr.9.cfg"

But, I can't get to that folder. How to turn on my monitor display?

Debian Multimedia :: Triple Monitor Setup On Wheezy

Apr 29, 2015

I have some very strange issues with my tripple monitor setup on debian wheezy. I have acer aspire V3 laptop with i915 Intel (Intel® HD Graphics 4000) as part of i3 and nvidia GT 740M which I never managed to get working with or without optimus to any degree whatsoever. What I want is a reliably working triple monitro setup. I have 2 additional DELL u2412m monitors which I did manage to get to work on few occasions by more or less randomly turning stuff on and off via lxrand and KDE systemsettings (so I do knwo for a fact that tripple monitor setup works). Arandr doesn't work, and executing xrandr from cmd doesn't work. I can relatively easily get the 2 monitors to mirror each other, but to get them to work separately is extremy difficult. It's always the same error but the well known crt. For example:

xrandr --output VGA1 --mode 1920x1200 --pos 3840x0 --rotate normal
xrandr: Configure crtc 2 failed

xrandr --output VGA1 --mode 1920x1200 --rotate normal --right-of LVDS1
xrandr: Configure crtc 2 failed

When it did work I copied arandrs script in hopes it would work, but it doesn't. Obviously, here is the issue that the crtc can not be configured so if somoen could tell me why and how to get the damn thign to use a specific crtc it would be awesome. Also, I noticed that when I hit "identify monitors" in KDE systemtools, it would say VGA HDMI for both VGA and HDMI outputs.

Here is xrandr output from when it worked:

Code: Select allScreen 0: minimum 320 x 200, current 5760 x 1200, maximum 8192 x 8192
LVDS1 connected 1920x1080+1920+0 (0x46) normal (normal left inverted right x axis y axis) 382mm x 215mm

        Subpixel:   horizontal rgb
        Gamma:      1.0:1.0:1.0
        Brightness: 1.0

[Code] ......

Here is now:

Code: Select allScreen 0: minimum 320 x 200, current 3840 x 1200, maximum 8192 x 8192

Debian Installation :: Monitor Signals Out Of Range On Reboot

I am running an AMD Athlon 64 with an NVIDIA 6600 video built into the motherboard (PC Chips). My monitor is a 19" LCD with a standard VGA connector. I tried installing Lenny and everything went smoothly. However, when I rebooted, the monitor said "Signal out of range." I had this happen with a live CD of another distro too.

Ubuntu Servers :: Apache No Longer Starting Unattended After Reboot?

Nov 18, 2010

I have an Ubuntu 10.04.1 AMD64 server running Apache with SSL. In the past, even though I have a passphrase on my key file, I have only needed it if I manually restarted Apache2, never after reboot.

I recently switched from a self-signed cert to one from a CA. I'm not sure if this is what caused it, I also installed a few packages (AWStats, PHPSysInfo and Munin) that all interact with the webserver.

Anyway, I just noticed that now after a reboot Apache starts but doesn't work. I need to kill that process and start a new one with the passphrase (maybe on the console it is prompting me, I mainly use SSH access since the server is headless).

Why did Ubuntu used to 'remember' the passphrase on the self-signed cert but now I need to provide it?

My sever auto-updates so it would be annoying to have this thing go down regularly after a patch that requires a reboot.

Ubuntu Networking :: Network Manager No Longer Seeing Devices After Reboot

Dec 5, 2010

I just loaded 10.10 on an Acer Aspire One D255. When I installed Ubuntu, network manager loaded and I was able to use both the wired and wireless cards. After I used update manager, the kernel was upgraded, and I also added some wireless applications (RutilT WLAN Manager, SWScanner, and WiFi Radar). Upon reboot, the network manager doesn't work, and it cannot find any of the devices.

CentOS 5 Server :: ISCSI Volumes No Longer Mount After Reboot?

Sep 22, 2011

We have a Centos 5.6 server mounting two iSCSI volumes from an HP P2000 storage array. Multipathd is also running, and this has been working well for the few months we have been using it. The two volumes presented to the server were created in LVM, and worked without problem.We had a requirement to reboot the server, and now the iSCSI volumes will no longer mount. From what I can tell, the iSCSI connection is working ok, as I can see the correct sessions, and if I run 'fdisk -l' I can see the iSCSI block devices, but the O/S isn't seeing the filesystems. Any LVM command does not show the volumes at all, and 'vgchange -a y' only lists the local boot volume, not the iSCSI volumes. My concern is that, the output of 'fdisk -l' says 'Disk /dev/xxx doesn't contain a valid partition table' for all the iSCSI devices. Research shows that performing the vgchange -a y command should automatically mount any VG's that aren't showing, but it doesn't work.

There's a lot of data on these iSCSI volumes, and I'm no LVM expert. I've read that some have had problems where LVM starts before iSCSI and things get a bit messed up, but I don't know if this is the case here (I can't tell), but if there's a way of switching this round that might help, I'm prepared to give it a go.There was absolutely no indication there were any problems with these volumes, so corruption is highly unlikely.

Ubuntu Installation :: ASUS A8V-MX Recognises SATA Hard Disk?

My dual monitor no longer works. I downloaded the new patch for my video card and apparently the NVIDIA GeForce 8800 and Linux do not like each other?

1)Should I just remove the driver?

2)If I did would the old driver pick up because although it had a few faults, at least I could use both monitors after a lil engineering

3)If I were to remove the driver, where would I do it from?

Slackware :: KDE 4.6.0 (from Alien Bob's Ktown Repo), Battery Monitor No Longer Works?

Feb 22, 2011

I am running Slackware64 -current. I just upgraded KDE to 4.6.0 from Alien Bob's ktown repo, and upon doing so my battery monitor no longer functions properly. More specifically, the icon will appear in the panel, but when I choose the option to show the charge/discharge state it does not show. The icon only ever shows that the battery is not plugged in to an external power source (showing a plug and a red x). It is important that I get the battery monitor functional once again as I am running my new Slackware64 -current install on a laptop and don't like to be left wondering when my laptop's battery will die and if I need to plug it in.

Ubuntu :: Won't Save Monitor Settings Upon Reboot / Sort It?

May 4, 2011

So I have a fresh updated install of 10.10 on dell dimension 4550

The pc connects to my monitor through a dlink KVM switch so I can switch back and forth between computers.

When I reboot my monitor settings disapear and everything is real real large.

If i disconnect from the KVM and connect Ubuntu directly to the monitor and detect monitor it will allow me to adjust settings so everything looks normal. Until I reboot and I am back to the same huge icons again. If I try to go back and adjust monitor settings there are only 2 settings options because it does not see my monitor through the kvm switch again.

OpenSUSE Hardware :: Dual Monitor Setup Lost After Reboot

May 20, 2011

I'm trying to get an external monitor hooked up to my laptop with the intention to use both simultaneously using TwinView. Actually, I'm not "trying to make it work": everything works fine, using NVIDIA X Server Settings. However, when I reboot these settings are lost and I have to manually expand my desktop again.

I've found that running NVIDIA X Server Settings as root should allow one to "Save to X Configuration File", in order to let it automatically load the right settings. When I click this option, however, I'm asked to manually provide a file name with my home folder as the default location. I'm confused how to proceed - where should I save this configuration? Or should I be taking a completely different approach in the first place? (note: KDE 'Display and Monitor' doesn't work. Only when I use the NVIDIA-thingy KDE will recognize that my desktop is expanded to a 3600x1080 resolution)

Debian :: Squeeze Vs Wheezy ?

Nov 29, 2010

But when Squeeze goes from 'testing' to 'stable' in December... does Wheezy get promoted from 'sid/unstable' to 'testing' at the same time?.

I started my life in Linux with and currently use Ubuntu, and it runs decent(barely). However, I just upgraded to Ubuntu 10.10, and because of strange little issues and increasing bloatware, I have been forced to strongly consider the "mother OS": Debian.

The reason for my original question is that I want to run whatever the current "testing version" is. And if Wheezy gets promoted at the same time Squeeze does, then I will just wait the 4 weeks instead of slogging through another install(I prefer fresh installations vs upgrading within). I know the test versions of Debian are a bit more active than stable, but I have used Ubuntu for over 2 years, so I have some experience dealing with Terminal commands, package management, gnome, etc...I am also currently VirtualBoxing a copy of Squeeze.

Debian :: How To Upgrade To Wheezy

May 20, 2011

I got "stuck" with stable up to now and want to upgrade to Wheezy. But, although I've done this before, I'm having a dependency problem I wanted to ask about before breaking my system somehow. This is the /etc/apt/sources.list, ready for Wheezy:

[URL]

So, I regularly use aptitude as my package manager. After updating the database with aptitude update, trying aptitude full-upgrade gives me a huge of conflicts.

[code]....

But, if I use apt-get dist-upgrade, I get no conflicts. if I dist-upgrade with apt-get, will that affect my daily usage of aptitude (which I prefer)? I know APT is a single database and apt-get and aptitude are just different interfaces, but I guess differences might rise when marking packages as automatically or manually installed.

Debian :: Can't Install JDK 8 In Wheezy

Apr 19, 2015

I dont want openjdk packages on my system, in Kubuntu I had a few troubles with them trying to make SqlDeveloper to work around. So this is what I see after a java -version:

Code: Select alledgardo@debian:~$ java -version
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)
edgardo@debian:~$

I've been uninstalling openjdk from synaptic and with other few commands on the terminal so far and I think I probably broke it. I have no /usr/lib/jvm folder only /usr/lib/java/jdk1.8.0_45.But everytime I wish to start up Eclipse it shows the logo for a few seconds and that's it.... never gets opened. And in /usr/bin$ I only have this symbolic link....

Code: Select alllrwxrwxrwx 1 root   root          22 abr 19 18:57 java -> /etc/alternatives/java

I've tried different tutorials I found surfing the web but none of 'em seem to work.

Debian :: Spring On Wheezy But Not Jessie

May 19, 2015

I've had a weird issue recently with Java/Spring. Basically, it would work on all machines but my trusty Debian box. Macs for devs, Ubuntu for production and some devs have it too. This annoyed me, because of course Debian is the greatest and it must work there too! Also, Java is based on the whole write once run anywhere concept, I have never really had a problem with code behaving differently on different Java installs of the same version, even on completely different OSs it seems to behave itself very well. URL....

I moved up to Jessie and the problem goes away. I can only conclude that some library that is called by Java got upgraded, somehow influences the order in which Spring resolves its dependencies. Probably the fact that other devs build on Ubuntu and have got it working there, and the upgrade to Jessie brings my libs more in line with what Ubuntu will be running has done the trick.
