Ubuntu Installation :: How To Switch From Lucid 32 Bit To Lucid 64 Bit
May 9, 2010
I recently upgraded from Karmic to Lucid via the Update Manager. I would like to upgrade further by switching from 32 Bit to 64 Bit. I downloaded the Lucid 64 Bit ISO and wrote an install disk. When I reboot the computer with the install disk nothing happens.
Having a bit of an issue with my Lucid x64 HTPC. I can get the image to appear through DVI on a spare external monitor, but when it is disconnected and switched back to HDMI I get not picture on the TV any longer. I switched the sound output to an external USB device for testing the unit and noticed on reboot that I had lost everything via HDMI even though the setting had been switched back previously. Obviously a setting must be off here somewhere, but I've yet to find it. I've rebooted with only the HDMI connected, but still nothing.
I want to switch off 3d i.e. dri on my laptop to save power. There is a bug in the intel video driver that makes it generate excess wakeups and thus increase power consumption. I don't use 3d so this is very annoying.
I have tried modifying /etc/X11/xorg.conf to insert an "NODRI" option in the "Device" section and have commented out both of the "load dri" commands in the "Modules" section. No go. When I look in the xorg log, these changes are seen but not acted on. The system appears to have hardwired defaults set somewhere which are difficult to override. It appears to be a new issue because with Karmic one still had control with xorg.conf.
Just generally I don't like changes like this because it is not documented on the wiki where and how to change the defaults in Lucid. Linux was supposed to be easily configurable so IMHO this is a step backwards.
I recently installed Ubuntu 10 and when checking the version using system|about it says:
Code:
You are using Ubuntu 10.10 - the Maverick Meerkat - released in October 2010 and supported until April 2012. Now, I run some shellscripts and they check the distro. lucid-wx is not in supported versions but lucid is. Where can I change the lucid-wx to lucid?
Is it somewhere in a textfile or so? I cannot find it in /etc/issues or using man -n of man -a or so.
I have installed Ubuntu 10.04 lucid.I'm trying to install nvidia drivers from nvidia.com. And I need to stop gdm and use text interface.When I try #sudo /etc/init.d/gdm stop.It turn off gdm, but i can't get to login.
After upgrading to Lucid, I found that I still had a need for php 5.2, instead of the 5.3 that is installed during the Lucid upgrade. I tried the method found here:

I added in /etc/apt/preferences.d/php all the packages that I use for php, including libapache2-mod-php5, installed, and ran a2enmod php5 before restarting apache. However, my browser still tells me if I want to download php files on my server. I cleared the browser cache, a2enmod'ed again, restarted apache2 again, and still the same.
how to get php scripts running again on apache.
EDIT: I should note I can get SOME php files parsed by apache, but some are not parsed. All files reside in some subdirectory of /var/www/.
I want to convert a Lucid installation to UNR, so am I right in thinking I can download the interface from Synaptic to do it. Or is it necessary to download the full version of UNR?
I'm having a problem with a new install of Lucid freezing a few seconds after booting up. Completely frozen - ctrl-alt-backspace or alt-SysReq-R-E-I-S-U-B have no effect. The md5sum of the installation iso was all right, the disk check was all right, & the memory test was all right. It's a GeForce 5500 graphics card, but I haven't installed any special drivers. Booting up to the command line (netboot) helps a bit but it still crashes after from a few minutes to a couple of hours. From the command line I tried removing compiz & compiz-core but it makes no difference. I also updated the installed packages, including to the 2.6.32-22 kernel, but no difference. This has happened with Jaunty & Karmic, but Intreprid runs fine, as did Windows XP. Anyone have any ideas what I could do to find out the cause ?
I have in a box of parts two wireless NICs, an Asus WL-1380G V2 and a Trendnet TEW-423PI C1.0R.
Googling shows that people have had a lot of trouble with these two NICs in older Ubuntu versions. Am I likely to have any success with either of them in Lucid?
Is there a list of supported wireless NICs for Lucid?
Does anyone have any recommendations for a choice of NIC?
Tonight I installed Lucid(10.04) on my laptop, which is a VAIO VPCCW. The first problem I faced was the blank screen when trying to install Ubuntu. That was solved by pressing F6 and activating "nomodeset" Afterwards, I had to edit Grub, removing splash and quiet and adding nomodeset, to get it running.
Because of the low resolution and lack of support for effects, I intalled the proprietary driver for nvidia and restarted. Now I'm getting a message saying the display cannot be found etc and it is running is low graphics mode. When trying to open nvidia-settings, I get "You do not appear to be using nvidia X driver. edit your X configuration file(just run nvidia-xconfig as root) ... " And obviously, running nvidia-xconfig as root didn't change anything.
I was forced to move to Windows a month ago as a result of this issue(bought a new laptop) and now I see the problem is not resolved yet.
After installing lucid, if I select xp at startup all that appears is a flashing cursor. I have read other threads that report the same symptoms but I'n not familiar enough with grub to tell if I have the same problem. Below is output from boot info script.
<code> Boot Info Script 0.55 dated February 15th, 2010 ============================= Boot Info Summary: ============================== => Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in
My Windows Vista installation won't start after upgrading from Karmic to Lucid. If I select it on GRUB2, it leaves a blinking cursor on screen. And I tried doing the whole test disk thing and the boot info script. This is what my Results.txt file says
Canon MX320, MX330, MX860 printer installation on Kubuntu Lucid 10.04 AMD64 bit. I am sure Ubuntu Lucid is similar. Once I upgraded to Lucid 10.04 AMD64 bit I found that getting a Canon Pixma MX printer installed was not going to be easy. So I thought it help others if I posted my experience here. To pull this off you will need both the Debian package, (.deb), and the source package from either
Canon Europe: [URL]... Or Canon Australia: [URL]... NOTE: The only reason to get the source is to access the ppd files. They are in the Debian package but it is a lot more work to walk newbies through unpacking the .deb. Since there are errors in the source code it makes impossible to compile a driver. Therefore, you will need to install the 32bit Debian package and force the architecture, then add the correct printer driver from the ppd file in the source package. While these instructions worked for me there are a few assumption I make which mat affect your outcome. My MX860 has a wireless network connection.
In other words I have no idea if this will or will not work on a USB attached printer. (If someone would be kind enough to post back if they get that configuration working that would be cool.) The other assumption is that the general reader is relatively new to Lunix and the command line interface. The commands were cut and pasted from my working kconsole, so they should work for anyone.Here we go:........
i tried update-manager -d from GUI and asked to downlaod 678 MB...so i downlaoded the i386 iso 685 from cdimage.ubuntu.com/alpha-3..now how to upgrade to 10.04 lucid alpha 3 from 9.10.
I'm planning on going from Crunchbang 9.04 back to Ubuntu Lucid Lynx. My main concern is drivers and such. I have an Asus K40 with 4 gb ram, and Nvidia graphics cards. Last time, I had a disaster with Jaunty. The suspect is Gnome, as Crunchbang works. Is there a chance that I could have issues using the 64-bit 10.04 LTS? I need a stable system. It is going to take me a while to set up the new system so I want to make sure I'm prepared for any issues. I'm doing a clean install. I can pull up hardware types, etc, if need be later tonight.
When you install Ubuntu, you will typically install a complete desktop environment. It is also possible to install a minimal set of software (just enough to boot your machine) and then manually select the precise software applications to install. Such a "custom" install is usually favoured by server administrators, who prefer to keep only the software they absolutely need on the server.
I have never personally noticed any sections in the install to allow you to do a custom minimal install, is this possible in Lucid?If so how, or do I need to download just a mini install iso?
A clean install on an all linux AMD desktop machine. Problem is lucid will not shutdown. All that you can see is the background staring at you for good.
I'm currently upgrading my laptop, and it has completed the step "Getting new packages", and is now onto "Installing the upgrades".It says it is going to take another 2.5 hours, but I am leaving work soon and want to take the laptop with me. Is it safe to disconnect it from the internet at this point? I don't want to fudge up the install, but I don't want to have to leave my laptop at work all weekend (or have to come back and pick it up at some point).
I've recently upgrade ubuntu 9.10 to 10.04 LTS using my system update and after it had completed installing the packages. I shut down the computer.Then after I get home, I open my computer I have found out that the system is unable to mount my filesystem. I went to manual recovery, typing in fsck -y /dev/sda1 then after it runs, it said the system is clean. So then I type control d to reboot but then it said that the system I not ready or present and I continue to wait. It seemed that there's a major issue mounting partition in my computer, I'm not sure if NTFS has any involvement.
I have tried out Lucid Lynx Beta 1 back in march. During the installation I was announced that support for bluetooth was dropped. I installed anyway, thinking it would be back in the Final Release. Meanwhile (between March and April) I reinstalled Karmic because I really needed the bluetooth. I can see in the upgrade that bluetooth still isn't available. What should I do about this? Is there a way to keep Lucid Lynx and bluetooth? Or will I have to stay on Karmic until the end of times?
When a USB device is attached to the laptop 10.04 does not automount the device. i.e. the device, be at an external drive, memory stick or iPod does not display with the correct icon on the desktop.
However, if one looks under Places|Computer there they all are with the correct icons. The devices can then be mounted from there.
This issue seems to be related to these other posts: [URL]
This is really disappointing given that 10.04 was promoted on its iPod friendliness!
System: IBM Thinkpad T41; Pentium-M 1.6GHz; 1Gb RAM
How to go about in this situation with a 64-bit version of Lucid, and XenApp? Citrix only has 32-bit packages available on their web, and previously with Karmic, you just added some 32-bit libs, and it would work. But now the "GDebi Pack*ager Installer" refuses to do the install, since this is a 32-bit package, and throws you this error: "Error: Wrong architecture 'i386'". Anyone out there that has managed to find a workaround to install this?
I've tried various searches and haven't found anything quite matching this. Please forgive me if I am repeating though. I upgraded my Dell D600 (ATI Mobility Radeon 9000) from Karmic to Lucid. On Karmic, all 3D effects (Expo, Rotating Cube, etc.) worked fine. On Lucid, all still work but, once once enabled, the 3D effect is very dim - almost as if the backlight on the effect itself is turned off (i.e., when rotating the cube, the cube is dark but the background Skydome is illuminated). Once the effect is over, normal illumination returns. Running Karmic from the live disk and the effects are fine again. A buddy upgraded his D610 (next ATI in the line) and does not have the same issue.
I upgraded successfully last night from Hardy Heron to Lucid Lynx, but have no sound now. After searching around I can see that this is a fairly common problem. But none of the proposed solutions that work for other people have yet worked for me.
If I type 'alsamixer' at the command line, everything looks fine. There are no 'MM's indicating something being muted. I tried removing and reinstalling alsamixer and pulseaudio with no success. Edited lines 45 and 46 of /etc/pulse/default.pa with no luck.
I have a dual boot system with Win XP and Ubuntu (using grub boot menu). I recently upgraded my Ubuntu from 9.04 (Jaunty) to 10.04 (Lucid) and now I cannot boot into Ubuntu - I just get a desktop with no icons or disk activity. I think this may have something to do with the fact that I answered 'no' when asked whether to replace my menu.1st file, and possibly some others. So my boot menu still refers to 9.04.
