Users / Core/Hybrid Dual NIC's Dual MTU speeds.

« on: May 29, 2014, 03:24:17 pm »

Hi,

I've been playing with jumbo frames on my "Media Network".

On the Core one ethernet card is set to mtu 1500 going to the DSL modem (default - can't be changed).

The other ethernet card is set to X000 mtu going through a switching hub (supports up to mtu 9000 speeds) to 2 MD's whose mtu set to matching X000 speed.

The NAS is matching the X000 mtu.

I can use jumbo frames within the Media network, (for movie playback, etc.), but when I want to do, for example, apt-updates/upgrades it fails big time because of the dropped packets from the DSL modems 1500 mtu speed.

Is there a way in the Core to handshake between the 2 different ethernet cards running at different mtu speeds?

I've looked around but haven't (as yet) found anything that addresses the topic.

Thanks.

Installation issues / LMCE 1404 Initial Install Notes for Core/Hybrid system.

« on: May 19, 2014, 10:08:09 pm »

Hi guys,

1) I did not select "Install this third party software".

2) Under computer name "Geforce-8000-series-invalid-entry-length-0-DMI-table-is-broken-Stop" message received.
   Same on 12.04 install.

3) Liked the return of "please remove installation media and close the tray (if any) then press ENTER:".

4) Selected *Ubuntu on Gnu Grub menu.

4) Ooooh - fancy glowy kubuntu!

5) System booted temporarily into kubuntu desktop - then restarted with Grub memu.  Selected *Ubuntu.

6. Received network messages (including 60 seconds and booting without full network).

7) Got AVWizard after selecting initial screen size got lots of error message...
systemd-udevd[XXXXX]:failed to execute 'lib/udev/socket:0/org/freedesktop/hal/udev_event' 'socket:0/org/freedesktop/hal/udev_event': No such file or directory

DVI/HDMI (first choice) with analog audio selected.

   Screen ratio:       16:9
   Video output:      DVI
   Video resolution:   720p
   Video refresh:      60
   Audio connector:   Analog Stereo
   Dolby sound test passed: not available
   DTS sound test passed: not available

9) Upon "I agree" again got lots of...
systemd-udevd[XXXXX]:failed to execute 'lib/udev/socket:0/org/freedesktop/hal/udev_event' 'socket:0/org/freedesktop/hal/udev_event': No such file or directory

10) Then...

    0
    ConfirmDependencies Install is running
    ConfirmDependencies Install is done
    InstallNewDevice is running

    ...looking good.  Wait for it...

    ... after 32 minutes on my system received LMCE installation screens.

11) After 2 hours I'm still waiting for Sarah to say "hello".

    I opened a terminal window - OK that works.

    The first thing reported by the dcerouter login: ConfirmDependencies buildall is running.

    I logged in.  It worked.

    Running 3.13.0-24-generic.  Have name@dcerouter:~$ prompt.

    Logged in as root.  Have dcerouter_1:~# prompt.  Switched back to F7 - nothing, then back to F1.

    Did top - flipped around between top, asterisk, ksoftirqd/0, mysqld, StorageDevices_, rcu_sched, etc. but nothing hogging the cpu.

    Nothing ran as a heavy user.  Nothing of the conssistant programs ran above 1%.

12) I will let the system run for up to 4 hours.  At that point I will reboot to see if anything develops.

Oh! Just great.  I lost power.

System is restarting.  Booting without full network configuration.

I'll save this now, just in case I get dumped again.

Cheers.

Installation issues / Why have the recent snapshots only been 2.5gig?

« on: May 18, 2014, 01:42:47 pm »

Hi,

I am very reluctant to download for testing.

The last time they were small there was no networking.

Just curious.

Installation issues / eth0 and eth1 kernel driver in use - Resolved..

« on: May 15, 2014, 07:28:35 pm »

Hi,

I have a Realtek RTL8169 chip for eth0 and a Realtek RTL81111/8168/8411 for eth1.

I downloaded and installed the r8168 driver from Realtek.

eth0 shows kernel driver in use:r8169
kernel module r8169

eth1 shows kernel driver in use:r8169
kernel module r8168, r8169

How do you get eth1 to use the r8168 driver?

If I blacklist the r8169 driver eth0 dies completely - ifconfig only shows eth1.

I've tried creating alias eth0 r8169 & alias eth1 r8168 in various mod* types of files (plus other things) but nothing seems to work.

Is this even do-able?

Cheers.

Installation issues / AVWizard Failed to setup X.

« on: May 07, 2014, 11:56:05 pm »

Hi,

I reloaded 12.04 20140416153928950 from scratch, got the networking sorted out with interface swap, PNP'd my NAS and then restarted AVWizard through main menu >Advanced>AVWizard setup.

System restarted and I received AVWizard Failed to setup X message.

On reboot I get terminal message (system frozen) [screen a little wonky - large font]

No updates were applied.  System is running on default nouveau drivers.

I am going to re-install, get networking up (no NAS) and install nvidia-current to see what's happening.

Results will be sometime tomorrow.

Cheers.

Installation issues / 12.04 audio issues - Closed

« on: May 07, 2014, 03:48:01 pm »

Hi,

I messed up my system doing some tests and reloaded snap 2014/04/16 28950 from scratch, did an update/upgrade.

My audio is not functional.

AlsaMixer v1.0.25 shows my Card: HDA NVidia Chip:SigmaTel 92HD206X

lspci shows Audio device: NVIDIA Corporation MCP72XE/MCP72P/MCP78U/MCP78S High Definition Audio (rev a1)

Original install NVidia was the audio chip pci 07 and I was analog stereo.

I restarted AVWizard - now have AVWizard Failed to setup X message.

Will reload from scratch.  Test system.  If successful will update/upgrade to see if something there is an issue.

Cheers.

Installation issues / xine cpu 80% with vdpau

« on: April 21, 2014, 10:57:58 pm »

Hi,

I've been doing some tests, (before I try jumbo frames), and I've notice that while playing a DVD (VOB) from my NAS to my Core/Hybrid, or to a MD, xine has been running at 79-80% CPU.

This is with both hardware acceleration & De-interlace quality set to vdpau with video card defaulted to GeForce.

Picture looks great but it seems strange that CPU % is so high.

I've tried stuff but with little success at reducing CPU %  (which I didn't think would be that high in the first place).

Am I'm wrong thinking this is an issue?

Cheers

p.s. 12.04

Installation issues / Gigabit ethernet card runs @ 100 - Resolved

« on: April 18, 2014, 10:24:58 pm »

Hi,

Before I get too stupid and spend hours/hours looking into things... would a 1 Gigabit card running r8169 driver get stuck @ 100 speed?

Everything works fine except the speed.

I want to set up jumbo frames on my LMCE network because my MD's are not the fastest CPU's.

I was hoping to increase the frame size, reduce my CPU processing and improve my data transmission speeds.

I have one device in the network which is connecting @ 100Mbps @ the switching hub but "spec-wise" has a gigabyte card.

Other devices are 1Gig at the hub.

Cheers

Installation issues / Snap April 13 28939 ehci_hcd errors - Kinda

« on: April 15, 2014, 09:26:37 pm »

Hi,

On this snap (could have been earlier as well) I received a...

 /sys/bus/pci/drivers/ehci_hcd

...error on usb 3-4 at boot up with lots of usb 3-4: device descriptor read/64 and device not accepting address XX messages .

So I ...

cd /sys/bus/pci/drivers/ehci_hcd

and did ...

ls -l

In my case this displayed two files with 0000:00:XX.X names.

I entered the command...

echo -n "0000:00:XX.X" > unbind

for both files and this slowed the messages down quite a bit.  At least it made it easier to enter command prompt entries without having everything overwritten by the terminal output messages.

This had to be re-entered every time I rebooted.

So I put the commands into /etc/rc.local and rebooted.

echo -n "0000:00:XX.X" > unbind /sys/bus/pci/drivers/ehci_hcd

They don't come up as nearly often but they still annoy during troubleshooting.

I don't understand why they still pop up - period, but it's way less annoying than before.

Cheers

Hi,

Looks like some error reporting was turned on.

The handshaking between LMCE and DNS 323 NAS continues as reported in http://forum.linuxmce.org/index.php?topic=13577.0 reply #19 but I am now getting flooded with (it is spring) a few    Error connecting to socket - aborting operation     and continuous...

Installation issues / xrandr & gtf question.

« on: March 17, 2014, 04:09:00 am »

Hi,

If xrandr doesn't show a particular screen resolution - for example 1280x720 does that mean my monitor will not be able to exactly reproduce that resolution?

Even if I plug in a modeline supplied by gtf?

Cheers.

Installation issues / Small LMCE screen size (Resolved on Mar. 25 48288 load).

« on: March 15, 2014, 09:24:15 pm »

Hi,

In 12.04 with CRT and VGA screen I had this issue...

http://forum.linuxmce.org/index.php?topic=13459.0  see reply #6

...(CRT/VGA/8400GS) and I managed to get around it.

Now I am using completely different hardware (HDTV monitor (1680x1050 max), DVI/8500GS) and adding a modeline and modes either kicks me out to command prompt - no X window and I am provided with a small LMCE window.

I have tried AVWizard in various configuration 1080, 720, etc. but no luck.

I have tried various xorg.conf setups.

When I go to KDE desktop (via LMCE menu) the KDE screen is properly rendered.  Only LMCE screen is small.

Cheers.
