Debian Multimedia :: 2560x1440 60Hz Doesn't Work Over HDMI On Testing
Aug 12, 2015
I just got a new Dell monitor (U2715H), and even with beta Nvidia driver (355.06) on Debian testing x86_64, it doesn't detect highest resolution (2560x1440) when connected over HDMI to Nvidia Geforce GT 620. I have an HDMI 2.0 compliant cable, and according to Dell reps, the monitor should support 2560x1440 over HDMI.
Some suggested using xrandr to set the video mode explicitly. I tried doing it, and first got a EDID file with nvidia-settings, and run edid-decode. Where is what I got there:
Code: Select allDetailed mode: Clock 241.500 MHz, 597 mm x 336 mm
        2560 2608 2640 2720 hborder 0
        1440 1443 1448 1481 vborder 0
        +hsync -vsync
So I used those values to make a new mode in xrandr:
Code: Select allX Error of failed request:Â BadMatch (invalid parameter attributes)
 Major opcode of failed request: 140 (RANDR)
 Minor opcode of failed request: 18 (RRAddOutputMode)
 Serial number of failed request: 31
 Current serial number in output stream: 32
I'm running Ubuntu 10.10 with an EVGA nForce 730i Intel mobo with onboard HDMI. Video output works. Audio output does not. I'm trying to output both to a Samsung HDTV.
I tried booting to a bootable drive with Ubuntu 11.04, and no audio.
I've essentially tried everything in every other thread. I'm using alsa mixer, I've muted S/PDIF, my settings all have HDMI output selected.
sudo modprobe snd-hda-codec-nvhdmi results in:
Code:
aplay -l results in:

Also tried aplay -D to play a .wav, and heard no sound, but also encountered no errors.
I created a very simple cron job for testing my first Linux system but It doesn't work. After open the crobtab file by typing crontab -e, I put a line like this to send email in every 2 minutes to report disk usage:MAILTO=dan@gmail.com*/2 * * * * du -s /homeI tried to restart cron several times but I still got nothing worked. /etc/init.d/crond restart
I've seen this problem on dozens of different forums but I haven't found anybody with my specific problem or a solution that has worked. I have an nVidia GeForce 8400GS which I just installed in my Debian box and I can't get the HDMI audio to work. Kernel version is 2.6.32-5-amd64, nvidia driver version is 260.19.36, alsa version is 1.0.21. Output of lsmod shows that nvidia module is loaded. Output of aplay -l code...
I feel like I've looked everywhere on the internet for a solution to this and I just can't find one. It seems that everybody is able to see their nVidia audio device using aplay -l and then the solution goes from there.
I'm trying out a Jessie install and have noticed VNC doesn't work as well as it used to. I often install a desktop environment on a headless machine, disable *dm, and use vnc4server to create a desktop session if I want to use a GUI. When I try to do the same on Jessie, I run into problems.
Using Gnome, all I get is the generic "Oops something went wrong" error. Looking at .xsession-errors, there are some errors that hint at the problem.
Code: Select allXsession: X session started for ryan at Mon Dec 29 06:07:30 CST 2014 X Error of failed request:Â BadValue (integer parameter out of range for operation) Â Major opcode of failed request:Â 109 (X_ChangeHosts) Â Value in failed request:Â 0x5 Â Serial number of failed request:Â 6 Â Current serial number in output stream:Â 8

The same thing seems to happen with Cinnamon. Since I doubt a fix for the above issue will make it into Jessie, I tried XFCE. However, that doesn't work correctly either. When running XFCE via VNC something is misreporting the version of xrandr as 1.1 instead of 1.4. Since xfsettingsd appears to want version 1.2+, many things are broken.
This post on the Ubuntu forums suggests the issue might be fixed in xfsettingsd version 4.11: [URL] .....
Is there a better way of getting a remote desktop in Jessie that I'm overlooking?
I have installed VirtualBox and since then resuming from hibernation doesn't work again (my previous thread: [URL] ....). My question is: Can VirtualBox kernel modules (vboxpci, vboxnetadp, vboxnetflt, vboxdrv) break hibernation? If yes, what to do? Maybe unload them before hibernation, blacklist when resuming and load after resume? And how to do that with systemd? URL....
I installed the adobe plugin, and my browser crashes. I uninstalled it, and installed the one in the apt repository (mozilla-plugin-gnash) and it shows up in my about: plugins in iceweasel, but flash just doesn't play.
I'm running newest pidgin on sid and i have few problems. First of all notifications doesn't work (plugin is of course turned on), also even when i turn on blinking icon it's not blinking. Oh and why the tray icon is so small now?
I have problems with xrandr in a system with Nvidia GeForce 8600GT video card. I want to use xrandr to rotate the screen on the fly.

I tried enable the last option, change values for xinerama and twinview, but nothing works.
Just as the title says: I installed iceweasel 6 in debian squeeze (via mozilla.debian.net) and while errors and requests are captured in the web console, I simply cannot use it to evaluate arbitrary javascript I type in it.
Does anyone have this problem as well? It's been like this since v5 as well. I already tried purging and reinstalling, as well as running with another profile.
I tried to do Debian netinstall from minimum iso image in my brother's pc. My Network Interface card is Intel 82578DC GIGABYTE Network Connection. The installer gives a list of drivers to install but I don't know what to do. Should I download and install from first CD/DVD? Will it have appropriate drivers then?
After the latest update of network-manager-gnome to version 1.1.90-3 , I see that I have to start the nm-applet in Testing from a terminal, otherwise I can't bring up my wired connection.
The usual nmcli networking on command is failing to connect, also restarting the network-manager.service with systemctl doesn't do anything, the only way to connect at this time is indeed to manually start the nm-applet from a terminal.
I've also spotted this message in the logs:
Code: Select alltraps: nm-applet[1105] general protection ip error:0 in libgobject-2.0.so.0.4600.2
Could it be something wrong with my configuration (although , it worked before this update) or is it some bug in network-manager-gnome 1.1.90 ?
I've tried installing both ibus-anthy and ibus-mozc in Jessie but I still cannot input Japanese.
By contrast, In Wheezy, when using anthy for example, I can see ibus preferences icon where I can configure ibus and anthy. This doesn't show up in Jessie.
I recently install a Debian 8.0 Jessie on a Laptop Dell latitude E6540 with gnome 3.14+3. But the problem is that it doesn't recongnize my multimedia buttons, I tried some methods but I didn't get results.
$showkey --keycodes volume up  -- 115 volume down -- 114 volume mute -- 113

When I reassinged the keys on Settings>Keyboard>Shortcuts to F7, F8 and F9 it works, but when use the keys volume up, down and mute It doesn't show anything.
The same happens with Fn + Brightness keys, in this case it worked the first time but then stop to work I don't know why..
I am having trouble getting evolution to work properly with my imap server. It won't show any messages. Icedove works fine, though. I'd rather use evolution because of the calendar. I'm not sure what I am doing wrong. The IMAP server is hosted by network solutions. I have screenshots of both clients. I've blacked out a few things for privacy.
I've successfully installed Debian testing (squeeze) on my old iMac G3. I didn't select a desktop environment as a preconfigured package, but only left "standard system utilities" checked.Once I rebooted, I logged in as root (on the command line) and ran "apt-get install xfce4 xfce4-goodies gnome-icon-theme xdm", let all that pull in and installd then rebooted. As the system was booting, I could see all the services starting and whatnot, but when it gets to the line "Starting xdm..." the screen changes to black, but stays black for a good 2 minutes. I tried hitting some keys on the keyboard, as well as typingy login credentials, even though I can't see them, but nothing seems to work. I've tried rebooting several times

not sure exactly when this broke, but for some reason I'm not able to use CTRL-ALT-F1 anymore to fall back to the first virtual console.I can kill X with CTRL-ALT-BACKSPACE just fine, but I'd like to be able to get a normal shell to kill things when I've messed too much with graphical stuff.

Every time I boot my machine, some of the playback values in alsamixer are set to 0 and are muted, so I have no sound.
The thing is, I have tried setting these to normal levels and then run sudo alsactl store. Then, if I run sudo alsactl restore after I reboot, the sound comes back up. However, if I have alsactl restore in /etc/rc.local, it doesn't work: I still get muted sound when I reboot. I have to run sudo alsactl restore manually each time.
I have already checked whether /etc/rc.local runs at startup, and it does. Also, I know that /var/lib/alsa/asound.state contains the correct values, because when I run sudo alsactl restore, the sound returns to normal levels. So what remains is either alsactl restore doesn't work in /etc/rc/local, or something runs after it and mutes the sound.
I have some troubles with my microphone.I can hear it in ootput if I knock on it or speak, but I can't record from mic. It also does not work in skype.cant figure out what is the problem.
I'm having problem to get my sound work on my HTPC based on Asus AT5IONT-I Deluxe motherboard. I can get analogue sound out but not the digital sound on HDMI nor optical. I have tried a couple of things I've found on swedish forums, but nothing have worked so I'm ready to start over again from the beginning. I'm a real beginner when it comes to Ubuntu so step by step instructions is preferred. code...
i'm tryin to get a GPS dongale to work with debian testing on start up gpsd starts under nobody, (ps -C gpsd -fww) so i pkill it. i want it to start under my login so i try gpsd -N -n -D 2 /dev/ttyUSB0 this gives bash: gpsd: command not found if i tey (gpsd -N -n -D 2 /dev/ttyUSB0) in a root terminal or with sudo it launches,
[Code]....
i'm following a method i used on ubuntu to get this working so i think that launching gpsd under my username is the key
visit the link [URL] and read specifically the HDMI Audio section. Don't worry if you are unable to test for the sound. Connect the HDMI cable from the laptop to your LCD tv. This should be trivial. Make sure you switch your TV to HDMI input from its menu options. After enabling the HDMI configurations on your laptop using Step 1. Click on System--> Preferences --> Sound. Click on the Hardware tab. By default it might be set to Analog Stereo Duplex. Go to Output tab. Change the Connector drop down from Analog Speakers to Analog Headphones. Go back to Hardware tab and select Digital Stereo (HDMI) Output. Function+F5 would direct the video output to your TV. Incase you have a problem redirecting your video output to the TV. Restart your machine with the HDMI cable connected to your TV. With the configurations you would be able to hear sound from your TV. Have a blast! I have tried this with Acer 5738 it might work with other Laptop configurations as well.
I occasionally use a DisplayPort->HDMI cable to connect my laptop to my AV-Receiver, however I only get the picture to the AV-Receiver, but no sound. I read that not all DisplayPort->HDMI cables support sound, so I tested Windows7 on the same machine and it transmitted sound over that cable just fine. So I conclude that it is a Linux driver problem.
So I generally wonder whether this can be made to work easily or not. Does anyone here have experiences with this topic, especially with nvidia graphics cards managing the display port? (I did find older posts about HDMI audio, but they were all concerned with ATI graphics.)
pavucontrol / phonon do list a "High Definition Audio Controller Digital Stereo (HDMI)"-device, but sending sound to it does not do a thing. Furthermore, my dell laptop only has a displayport, but no HDMI connector.
This is what greeted me this morning. I think I'll leave it until after breakfast. Current status: 291 updates [+291], 3601 new [+1]. root@chaffinch:/home/eric# aptitude full-upgrade The following packages will be upgraded:
it worked fine, and fixed the black-box bug in cairo-dock, and i finally had a nice graphic bootscreen again.
but another bug occured: im running dual-screen setup, my notebook is connected via vga to a dell 22 inch widescreen TFT.
by default both screens running with 60hz and no problem.
now, after activating KMS it happend that, while the dell monitor still ran 60hz, the notebook screen was running with 61hz! it was shown in the monitor-options. the notebook monitor was therefore flickering a bit for 5 seconds, than running fine for another few seconds. then flickering again. (obviously, as 61hz is too much when it should run with 60hz!)
so my question is: how can i activate KMS again and have both of my screens running with 60hz again? is there an option?
