Ubuntu :: Lower The Resolution Of All The Images In A Pdf?
May 9, 2010
How to lower the resolution of all the images in a pdf? I searched around and couldn't find an answer to this. I have a pdf file of a textbook that I use in school but each page is an image of 2 pages of the textbook (left page, right page when the book is opened) and each image is of a very high resolution. I downloaded pdftk and pdfedit but for such a simple problem, I'm having trouble. Is there any way to do this?
I have tried converting the 380 MB PDF file to PostScript but after an hour of doing that, it stopped, and the PostScript only had about 17 pages instead of the 733. So converting it back to a PDF file to utilize pdftk's algorithms would have been worthless. I know I could split up the pdf file into sections but I'd rather just scale down all the images, or make them mid quality PNGs or high quality JPGs just so the filesize can be halved.

I needed Ubuntu server and recklessly picked Karmic. Hardware is some regular 775 mobo with integrated Intel graphics. Monitor is ASUS VH222D. Installation went smoothly but after that problems occurred. Shell is displayed in 1920x1080 resolution and fonts are so small almost unreadable. Grub2 looks OK, standard non-fb and so does few rows of text after loading grub but soon after that framebuffer becomes active.
dpkg-reconfigure console-setup doesn't mention resolution. Some articles are leading to grub2 gfxmode but none of manuals helped. I just cannot change grub2 menu resolution to anything else than standard console fonts (non-fb). Kernel option vga=XXX is no longer working.How to lower shell resolution? Why is this automatic???

I upgraded from 9.04 to 10.04.1 so I am still using legacy grub.Anyway, I noticed with the update that the console is using the framebuffer and using VESA for high resolutions.I really don't like or want this feature. So I added vga=0 to get 80x25 and it works initially but just when the X server is running (Xubuntu in my case) I can see how the console switches to a high resolution again. After this, if I go to a console, lets say tty1, it is using again a high resolution instead of 80x25 (VGA). Is there a way to force the consoles to be in a lower resolution and keep it that way? It used to work fine in ubuntu 8.xx and 9.xx

One day when i logged in, my screen resolution became lower. The sistem do not recognize anymore my old resolution (native) 1600x900 . And you can realize that maybe there are problems with the video card, because the system is slower than before in this terms. What could have happened?

This is some thing that I've noticed with any install of Ubuntu whether its regular Ubuntu or Kubuntu etc. The splash that comes up with the distro name Ubuntu/Kubuntu on start up look perfectly fine and as it should until I've installed my Nvidia drivers. then it goes all bung.
Lower Resolution. Slightly different colouring and Not taking up the whole screen. Sometimes it even sits slightly to the right.
Is there a way that I can fix this? I know its nothing all that major but it would be nice if it looked as its meant to.

I've recently got a HDTV LCD display (BenQ SD3742), and a nettop (Acer revo 3610) to go with it. I connected them using an HDMI cable, and I installed the latest Ubuntu 10.04 64 bits edition.I then installed the latest nvidia drivers (nvidia-current package, which is nvidia-glx-195) to support nVidia ION platform using this ppa: https://launchpad.net/~nvidia-vdpau/+archive/ppaAccording to various websites, my LCD is FullHD, so I should be able to select 1920x1080 resolution. But the automatically selected resolution is 1280x768, and in nVidia configuration panel, this resolution is stated as being "native resolution" for my screen (its name is correctly detected by Ubuntu, by the way!).If I select 1920x1080 and "Apply", the resolution is changed but the borders of my desktop are not available... and the image looks deformed anyway.Is there any way to make Ubuntu to detect properly this LCD display in its real native resolution (FullHD, 1920x1080)?

I am running Linux from a DVD, not installed. I am not good with installing software, but since the DVD cannot be corrupted, I am content to operate this way. Lately, I have been having problems that previously did not occur. When I try to click on the checkbox to get rid of emails, it doesn't register in most cases, or when it does, I am clicking multiple times so it registers twice, meaning it is unchecked again. Even more frustrating is some issues that are affecting my ability to update my business. I am trying to modify spreadsheets (text not calculations).
Whenever I try to click & drag to select something to change, it keeps jumping around to select only some of what I want, something else or some combination of the 2. When I try to copy and paste several fields from 1 column to another, everything from the several fields in the source column ends up together in the last field in the target column. I am also trying to download some images from a website. There is a single column of links to the images. I have to click on the link to get to the image in order to copy it, then back out to continue looking for more links to do the same.
My computer keeps jumping back 2 steps, then forward 2 steps, and sometimes I lose my place in that list. I could deal with it if it were a small number of links, but this is a list of probably close to 20,000 links. Again, i am operating off of a live DVD so this should not be corruptible, but this has just started happening, and has been an issue the last several sessions.

I know that ImageMagick's convert program can be used as follows to convert a collection of images -- say, in PNG format -- to a PDF file:
convert *png output.pdf
The problem with this is that each image is then stretched to fit on one page, whereas I would like to keep the original dimensions of the images and put as many as possible on one page in the PDF file before moving on to another page.

I am just spent half an hour hunting for a thing that should be totally available already:USB install images of Ubuntu, knoppix and all the others.And, the only good way are so far complicated tutorials where you extract the stuff from an CD image. Why??Hasn't everybody notices that CDs/DVDs are vanishing big time? That more and more systems don't have the readers anymore? Instead of following a 10 point instruction list, it would be nice to just be able to download a Ubuntu 8.10 or whatever USB image and be able to beam that DIRECTLY to a USB stick with a dd command.
Or am a missing something here? Does this exist?It should by no means be mariginal, considering how important USB stick in specific and flash memory in general have become.

I installed 10.04 1st by making a partition with bootcamp on MacOSX.Then I formatted the partition according to Ubuntu's instructions. I didn't install rEFIt, because I prefer to just hit the alt (option) key.I made the necessary adjustments according to URL...Community Ubuntu Documentation - and everything seemed to be working fine.I upgraded to Maverick and everything seemed to be working fine aswell.But then I noticed, that the wireless signal keeps failing and I'm asked to put the password again and again..
I don't think this is due to the upgrade from 10.04 to 10.10, but I just noticed it recently, maybe because of the air humidity, the signal was stronger a few days a go.. don't know!!Is there anything I can do?Perhaps install a new driver, or another wificlient, like Wifi-Radar??

I have an EEE PC 1000H, which comes with a 10.2" monitor with 1024X600 resolution. Ubuntu mostly works well on it, but on certain applications I cannot see the buttons that would appear at the bottom of the program. This has happened on the Disk Utility and Gnome Color Chooser

This is my third Ubuntu installation, and even with identical hardware, sound volume is dramatically less than under Windows. I turn every slider up all the way, and it is still less than half as loud as Windows.

I am really in need of expert help. I have started using Ubuntu last week, so a novice, and this is for my project work which needs a linux OS to install another programme (OOF).
I have installed 10.04 in an external hard disk and was able to use it without issues. While attemting istalltion of OOF it was giving me error messages and OOF forum suggested to use Ubuntu 9.04. So i have started installing 9.04 from the same external drive after uninstalling 10.04. I have used the live CD for both these installations. But Ubuntu 9.04 never completes the instalaltion. It is getting struck and aborted twice. My external drive is not partitioned and windows 32 bit is laptop -ACRE ASPIRE 5738, 250 GD HDD, Vista and 4 GB DDR.

I just recently installed ubuntu so I'm quite lost on some stuff. This little annoyance comes from the volume levels in Ubuntu 10.04. I have partitioned my computer to have dual boot into windows and ubuntu, so I know the problems are not related to the hardware itself as everything works just fine in windows. I am using a Dell Inspiron 9400, for reference.
The multimedia keys on the computer respond correctly but on the lower three volume settings sound completely drops out as if I had muted the computer. I went into the Alsa mixer to see if I could configure these sound levels and sure enough the master volume was down to zero, PCM and LFE are also low . I changed the settings of the lower levels but when I press on the volume up or down media keys to switch level the settings get reset. I tried just changing one level, exiting and saving through alsactl but it didn't stick. Even after reboot the settings are back to the zero volume on the first levels.

I have a keyboard with media buttons on it which work fine. I do have a question about the 2 buttons for lower and higher volume. Pressing the higher volume button increases the volume with a maximum of 18 steps, where step 0 = mute and step 17 is maximum. I wonder if it is possible to increase the number of steps to make the volume change not so big per step. Now I have one step which is a bit too loud, and one step lower is not loud enough.
