Debian :: Display Is Cloned Instead Of Extended
Jun 4, 2015
I'm having trouble with Debian 8 and using my dual monitor setup. Whenever I install a desktop that uses lightdm as a display manager (XFCE, MATE, Cinnamon) the login screen is cloning the two monitors rather then extending the desktop. I don't have the issue with gnome 3 (gdm) or kde (kdm). I tried installing Slim as well, but that has the same cloning issue.
I had a similar issue with g the XFCE environment, but I was able to resolve it by installing arandr and configuring the monitor layout. Upgrading from Stable to Testing also fixed the XFCE issue with the newest version of XFCE. Unfortunately I still have the display manager issue (lightdm/slim) in Testing as well. I would prefer to use XFCE but I'm willing to move to Gnome 3/KDE if need be to resolve the issue with the login screen.

How could xorg be set-up such that different monitors work with different DPI but still compose the same extended display?
I have a 15 inch laptop display extending to the right the main display which is 23 inch. The resolutions are comparable, but the difference in pixel size is very large. Thus, either the external display has too large fonts and UI, or the laptop one has them very small. Moving them at different distances is not entirely possible.
xrandr info:
eDP1 connected primary 1920x1080+2048+0 (normal left inverted right x axis y axis) 344mm x 194mm
VGA1 connected 2048x1152+0+0 (normal left inverted right x axis y axis) 510mm x 287mm
I heard that Windows has a hack (which I can't check) for extending displays with different pixels sizes: it computes in which of the displays a window has most of it's surface and sets the DPI for that window based on that. Thus a window will change DPI when crossing monitors, (and will look too small/large on one of the monitors if it is in the middle).

I'm trying to span my desktop across my 2 displays. I tried to edit xorg.conf-vesa to no avail.
Here is xrandr:
bash-3.1$ xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 1920 x 1600
HDMI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 510mm x 287mm
1920x1080 60.0*+
1680x1050 59.9
[code]....
I have attached a portion of xorg.conf-vesa and xrandr --verbose.

My current set up in OS X has an external monitor (Acer H243H) and my MBP 13" screen as an extension. The only way for me to currently get the menus and panes on the external monitor is to turn the Macbook display off. is there any way for me to change this?

I have extended desktop working on my netbook (finally, by turning off compiz), but now Gnome prefers my netbook's main screen as the main display (with the panel and such) instead of my external monitor.How can I switch this? I don't see any setting for it in the Display dialog.

I have XFX ATI-HD5670 and use proprietary catalyst 11.2-1 in 64-bit Fedora 14.
I am not sure when this started, or if it ever did work before, but when I started noticing that the screensaver will not turn off the monitor, I set the gnome power manager to make the monitor sleep after an hour.
Now, the display will not turn back on after it has been in sleep mode. I know the system is still running fine as I can ssh from another PC and see that everything seems to be normal, no error message in dmesg, /var/log/Xorg.0.log, etc.
/var/log/Xorg.0.log shows that monitor DPMS is not detected but still enables DPMS:
Is this a problem with catalyst driver? I know it's not the PC or the monitor, because I have a 2nd PC with the same video driver with the same problem, but others without this driver don't (ati open source, nvidia, etc. all work fine.)
I'm wondering if the problem always existed before, but I just didn't notice it because the display sleep mode was never set? If that's the case, my hunch is that it looked like it worked because the monitor was smart enough to turn itself off when the screensaver kicked in and just showed a blank screen, and the video driver was never involved with sleep mode until I set it in gnome power manager, at which point it started showing this problem of not waking up? And because the screensaver was no longer set to blank the screen, but to show some animation, that's why the monitor will never sleep anymore?

Im running Squeeze (in VirtualBox on a Win host), and I need to clone my drive to a bigger one and boot from that drive. I used gparted from a live cd for the cloning, and got the following result with fdisk -l:

255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Recently installed OpenSuse 11.3 on my system, Setup dual monitors w/ the latest Nvidia driver from Yast repo : download.nvidia.com
Initially twin view ( same desktop viewed on both monitors ) worked no problem
Once xinorama was enabled to extend the one desktop across both I encountered a mouse issue.
Main monitor is on the right, 2ndary on the left... When I drag the mouse from the right monitor over to the lest.. the cursor appears to get stuck on the left monitor's right hand edge.. it flickers as i move it around...
If I drag the mouse to the right a few whole mousepad lengths it will come back to the right...its like fighting to bring it back..

Simple question, which implies lot of complexity, unfortunately : how to install Clonezilla and mount multi-partitions cloned image disk under DEBIAN ?
Wishing that one day Linux would be so easy and complete as Windows. But we are gaining more users, so Linux will have more apps

I tried to access files from my old hard drive that used to be in a Mac (which unfortunately isn't working anymore). I connected it to my computer which I am running debian gnome on. So my question is how do i access a mac os extended disk image. The disk is encrypted and when i try to open it it says that i don't have permission. I think its encrypted in AES 128 bit.

For a fresh installation using manual partitioning, one single disk (IDE).
If I selected:
For the root partition, I would like to use ext4, 10GB, but by default, the partition type 'extended' is suggested. Would there be any difference (advantages, inconveniences) if I selected the primary partition instead?

Debian "squeeze" AMD64 Some filenames, containing accented or other extended ASCII characters are not shown both in Nautilus and Terminal, nor in Virtual Console.
I also noticed than when asking octave interpreter (ran from terminal) to display character range from 97 to 140 the output was:
On the other hand, when executing the same query in qtoctave the characters are displayed properly.
I've tried to change the font that the gnome terminal uses, to no benefit.
My default locale is en_us.utf8 and I am about to install every package that contains the prefix ttf
thank you for your time reading this

I am trying to set up dual monitors for lenny but nosuccess for the moment.
They were working fine for the same setup on ubuntu.
Using xrandr I get:
I read that virtual screen size could be the maximum part which is of no use in comparison to the current size.
So setting a virtual part in my xorg does not help much. If the above is right.
I have:

I had cloned my 250 GB HD to a new 1 TB HD using 'dd'. After that Ubuntu does not login. The MBR [Grub] and Windows 7 do start without any problem and all the programs are working perfect under it. When I boot to Ubuntu, the login screen just keeps displaying 'Automatically logging in...'. On the first boot from the cloned HD, Ubuntu displayed that the /home is not found and offered Check/Skip/Ignore and I selected Check. After that the message is not shown. Another weird thing is that at logon, the system does a log off and display a warning that the Power Manager Applet is not responding and asks for Log off anyway.
I have the old HDD intact with me.

I have 10.10 on an old 60GB hard disk in an external USB caddy so I can boot off this when I want to instead of Windows on the internal laptop hard disk. This works well, and has done for some time.
I recently got a 1TB portable USB drive and thought it would be cool to reserve the 1st 60GB for a clone of the 10.10 system and use that instead. So I set up 2 partitions exactly like the 2 partitions on my old disk (not forgetting the boot flag) and copied the contents with dd. I also used dd to copy the boot sector excluding the partition table (dd if= of= bs=446 count=1; dd if= of= bs=512 skip=1 seek=1 count=2047).

I work in a library and want to set up several newer PCs. I cloned a HD containing Ubuntu 9.10 using Clonezilla. When I put the HD in another computer (exactly the same as the one on which I did the cloning) it will not boot.
After pressing the power button, it proceeds as follows:
BIOS loads "Grub Loading" appears on screen for several seconds Ubuntu icon appears for several seconds Icon disappears and then nothing, blank screen
Regarding Clonezilla, I used the advanced screens but chose only the default settings.
Also, if I boot to the Clonezilla CD on the cloned computer, I can choose the HD and the OS loads without a problem.

I have a hp laptop with two internal drives and I also have a large USB drive. When I boot normally the internal boot drive is /dev/sda, the second internal drive is /dev/sdb, and the USB drive is /dev/sdc. I used Acronis True image to clone the internal boot drive onto the USB drive. I would like to be able to boot the Fedora 12 instance on the USB drive but do not seem to be having much luck... Here is what I have tried so far... The following is an entry in grub.conf
title Fedora (2.6.31.12-174.2.3.fc12.i686.PAE)
root (hd0,5)
kernel /boot/vmlinuz-2.6.31.12-174.2.3.fc12.i686.PAE ro root=UUID=101b1556-d097-4d85-9bc5-fac2f9abe5d8 LANG=en_US.UTF-8
[code].....
and tried to boot....Got a no such device error.While in grub I tried the grub command setup (hd2) and then got in the bios and set the boot order to USB drive before internal drive.In this case a reboot does nothing I just get a flashing cursor, grub is not entered.

I've been searching around and from what I've found this is supposed to just work but I am having some display issues when cloning my laptop to an external monitor. I think the problem is that my laptop has a better resolution than the monitor. Here is my setup:
laptop with a display of 1900x1200
external monitor with a display of 1680x1050
ideally I want to clone the laptops output onto the external monitor so they can both operate in their native resolution. When I setup twinview and set it to clone the laptop displays correctly, however, the external monitor is missing a large chunk on the bottom and right hand side
here's my xorg.conf
Code:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 1.0 (buildd@palmer) Fri Apr 9 10:35:18 UTC 2010
Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0" 0 0

I have an MSI Wind with Windows, Ubuntu Netbook Remix and another Ubuntu derivative installed on my 80gb drive. I recently acquired a 160gb drive, which I plan to put into the Wind. I cloned the 80gb drive, which left me with an identical configuration, plus 80gb of unallocated free space. The problem is that I already have 4 primary partitions; the last of them (adjacent to the free space) is divided up into 4 extended partitions. I tried to make the free space available in gparted, but it won't let me create a new partition because I already have 4 primaries. Is there some way I can get this into the last primary partition? I tried expanding the size of the extended partitions in the 4th primary partition, but gparted won't let me do this.

I have a strange problem. I have to clone my MAC address (and specify a different MAC address) to get internet. Without the new MAC address I get an IP address but no internet. This happened with my old (updated from 7.04 -> 10.10) OS installation and with a new, clean install of 11.04. So I have a workaround. But I don't know what the problem is.
Ps. I recently switch modem and router. And I had the problem with old and new modem/router combinations.

I have cloned an embedded system that runs Opensuse 11 x86 using dd. The embedded system uses a simple serial device, by writing to the relevant device file (/dev/ttyS2, usually). Curiously, when I write to the same serial device on the newly cloned system (which, incidentally, has almost identical hardware), thusly:
echo hello > /dev/ttyS2 the command blocks for up to a minute, before finally returning without making the hardware do anything. I can boot into Opensuse's rescue system on the clone and successfully do exactly the same thing, as I can when I boot the original's "identical" operating system. Why might this problem occur? What can I do about it?

I installed F11 x86 from the DVD onto one of my machines using a total of 4 partitions:
1. /boot
2. /
3. /home
4. swap
I then created an image of the first 3 partitions with fsarchiver and restored it onto a second machine (with different hardware). Grub was loaded onto the second machine as well without a problem. The new cloned install will get past grub fine but the kernel hangs. After removing 'rhgb quiet' from the boot options, I can see that the last message outputted to the console is something about the PS/2 mouse - this doesn't make sense as the mouse is working perfectly fine.
Additionally, I can still reboot using ctrl-alt-delete so the kernel/CPU must still be responsive. I have tried troubleshooting the various pieces of hardware, so I'm guessing it's something with the clone. All the cloned filesystems appear to be fully intact; the partition UUID's are all the same. I've even tried changing the UUID's both in grub and /etc/fstab to hardcoded /dev/sdaX , but this does not fix anything.

Installed Ubuntu along with Debian on my Notebook and use Grub Manager to choose between them on startup. Since i like Debian now a lot (in past days it was a very hard system to handle, but there has been some progress i noticed), i have to change some things (want Debian as main system now) For Ubuntu i have: (was meant to be main system on Notebook) "/", "/home" and a "swap" partition, but since i am now going to use mainly Debian, i wanted to store my files all in the "/home"-folder of my extended Ubuntu partition (has much more space available) not in the "/home" folder of the Debian system. So i want both (Debian and Ubuntu) to use the same extended partition ("/home") which i created for Ubuntu to save their files like downloads, videos, and so on.

I heard after I install debian, it could display Chinese information normally without any further work, but I have trouble to see all the Chinese characters.
So I googled and installed Chinese fonts, use dpkg-reconfigure locales to add Chinese support, but none of them work.
Here is my setup
