Ubuntu :: VBOX Setup Location & Memory Settings?
Jan 5, 2010
I have a few questions about VBOX.
My system now is a dual boot computer with Ubuntu and Winxp each on there own HD. The system has 4gb memory with a 512mb Nvidia video card.
1. If I understand it correctly, VBOX installs it's own copy of Windows to a directory. I can't piont it to the Winxp that I already have installed on the other HD?
2. VBOX has a two sliders for Memory, one for System and the other for Video. Do any of you have a system such as mine and would you have any suggestions for the two sliders settings?

As 2.17
I want to code this:
and byte[45],03
In words, AND the byte at memory location 45 with immediate value 03. As reports "Ambiguous operand size for and". How could I code the instruction such that as understands my intention?
john: .byte 45
and byte[john],03
gives the same error.

I tried to change the sys_call_address to another location in memory. The result was an OOPS!
sys_call_address is of course not exported, so I found it using:
Quote:
grep sys_call_table /boot/System.map-2.6.31-14-generic
c0577150 R sys_call_table
My kernel prog looks like:
Code:
#include <linux/string.h>
#include <linux/smp_lock.h>
#include <linux/init.h>
#include <linux/module.h>

Using openSUSE 11.2 & 11.3, where should I look for the default printer settings?
I have a Brother HL-1440 laser which for some reason prints right down to the bottom of the page cutting off the top part of the last line on that page. The default settings for the top and bottom margins are 0.50 inches. During installation using Yast2, the test page printed with correct borders.
When I change the bottom margin in options (from Ctrl-P), the page prints with the bottom margin set to 0.50 inch. The problem is I have to reset that margin every time I print a new document.
Where can I change that default setting? I've searched in /etc, /var, and /home but can't find it.

if you try to browse the web from the machine, or log in through a nomachine (nxclient/nxserver) session, it claims there is no internet conenction. You have to run System|Administration|Network and select the stored "Location" for our wired connection. There does not seem to be an option to make this (one and only) "Location" the default. If the machine is up and incoming connections are possible (samba & apache), surely outgoing connections should be working without extra fiddling?
The issue with nxserver (nomachine) becoming unavailable on a re-booted unattended machine (unless someone logs in AT THE MACHINE and runs System|Administration|Network) is causing problems for remote access.

I recently upgraded to Ubuntu 10.10 and I am experiencing an ultra high memory usage of the gnome-settings-daemon of 2GB after suspend! Killing and restarting the daemon solves the issue. Anybody else with this behavior?

I'm struggling to figure out the "right" dpi settings for my kubuntu setup. Currently ubuntu-karmic, kde-4.4.2, linux-2.6.33.2, and the new open source radeon drivers.I have a ThinkPad T400 with a 1440x900 14.1" display. That gives the display panel a resolution of 120dpi (see http://directedge.us/node/36).
'xdpyinfo | grep resolution' properly reports a resolution of 120x120 dpi.
However, 'grep DPI /var/log/Xorg.0.log' returns '(==) RADEON(0): DPI set to (96, 96)'.I initially had my KDE settings set to 96x96 dpi, as this "feels" more "right" to me. When I set KDE to 120x120, 8pt text seems pretty big, and the fonts in my gtk apps go crazy-huge. OTOH, a 72 point font should always be 1 inch at the proper resolution, and that is about spot-on at KDE's 120dpi setting (at least in native kde/qt apps; gtk is another story).I just want to use my display at its native resolution and have it look good all the way around. why radeon is logging 96x96 dpi to xorg.log, when the display is clearly 120dpi? I'm currently running without an xorg.conf. Is there an option to force dpi that I should add there?

In my computer with Ubuntu 9.10 the battery backing CMOS memory is dead (and replacing it is not an option). This requires from me to set up RTC time in BIOS each time I turn on computer (default date is from couple years back). When I don't set time, Ubuntu don't want to startup and it shows me fallowing message :
/dev/sdb1 : Superblock last mount time (Tue .... 2011, now = Mon ...200 is in the future.
/dev/sdb1 : UNEXPECTED INCONSISTENCY; RUN fsck Manually.
mountall: fsck / [842] terminated with status 4
mountall: Filesystem has errors: /
init: mount main process (840) terminated with status 3
Mount of filesystem failed.
A maintenance shell will now be started.
Is there any way to run Ubuntu without having RTC time set over, and over again in BIOS ? (It's acceptable for me not to have current time).

I am wondering if there is a basic tool out there that will work with graphics card powered by FOSS drivers that allows to adjust resolution (and configure secondary monitors) and then save that configuration so it can automatically be restored next time the system starts up.

I'm working with a program that uses Open Motif to create all of the widgets, including the Open File dialog box (obviously). However, Open Motif being kinda old-timey, 80's vintage, and for the most part now an abandoned project, it is quite clunky. So, actually what I need to do is to open some files located on my work server. I have already successfully connected to the relevant server directories with Samba, and with programs built with GTK+ (such as GIMP) I can open files across the network because I have created a bookmark in Nautilus, and those bookmarks appear in the Open File dialog box created by GTK+. Now, Open Motif is different: it doesn't see network locations, orNautilus shortcuts. When I type "smb://serveripyadayada" in the search folder, it really doesn't like it and complains. So, what do I do? Can I get somehow Open Motif to open a network location? Or can I do a run-around and place a shortcut in the file system that points to the network location?

I just set up a Squeeze server for a friend of mine using my exact apache2 settings. He has been playing around, having a bit of fun learning HTML, but he ran into a problem where one of his images would not display. I at first figured his HTML was incorrect, but after a very long time of trying to figure out the problem, I still do not know what is going on, so I think it must be an apache2 problem?[URL]..

I'm using Ubuntu 9.10 and recently installed Virtualbox PUEL edition that I downloaded from the Virtual box website. So I installed a virtual windows XP and it works fine. However, when the virtual XP is running, my computer can't go to hibernate when I click the hibernate button.The screen just turns black for several seconds and then brings me back to the login screen. When I shut down the virtual xp, the computer can go to hibernate the normal way.Why is it that running the virtual machine prevents my pc from hibernating?Is there a setting to enable hibernation while the virtual machine is running?

I put vbox on my wife's Dell Inspiron 6000 to play Netflix but the video won't play. After buffering it says there's an "internet connection problem". From what I've read that means the connection is too slow. Netflix works fine on my wired desktop (also Lucid+vbox) and on the same laptop booting into Windows (not VM). So I'm thinking there's a problem with vbox slowing the connection between the laptop's wireless and the VM?
I don't know if it will help with Netflix but 2D video acceleration is grayed out on vbox. Strangely, the 3D acceleration is fine and I can select it. If this is due to an unsupported video driver, can I change it?
