Change grub resolution from within grub console

Hello!
I'm looking for a way to change the grub resolution from within the grub console. Note, that I am not looking for a way to change the grub resolution in the config files!
This is why I'm asking: my laptop stopped booting whenever the grub resolution is not set to 800x600x32. This is very strange and I do not know the reason for this issue. It hasn't been a problem so far, because I'm just using the config file to set the resolution to 800x600x32.
Now I'm trying to reinstall, but the live discs won't boot since the resolution of grub is not 800x600x32. I tried dropping to console and typing
set gfxmode=800x600x32
set gfxpayload=keep
load_video
insmod gfxterm
but nothing happens.
So the question is: Is there any way to change the resolution of grub from its own console? Or is there a way to manipulate the live images before burning them in order to start grub with the desired resolution?
Thanks so much!

Did you add
terminal_output gfxterm
at the end. Although I doubt whether that will change the currently set menu resolution.

You may want to checkout grub-emu (available in grub-bzr aur pkg, not in core/grub). It emulates a grub menu from which you can test all graphics related stuff. I haven't tried it myself though.

Change scan resolution from HP Scan App iMac

I use the HP SCAN app to scan from my Photosmart. I like it because it lets me crop to constrained size. However, it seems to scan only at 200 DPI. I want a higher scan resolution. I know how to change it through System Preferences, but HP SCAN does not use those settings. How to I adjust the scan resolution from WITHIN HP SCAN application?

OK, from the HP Scan software click the Scan button.From there click the Down arrow () or the Show Details button to view and change any scan settings, including the scan resolution.

Hi fabiangs,
I'm not sure that I follow. Are you saying that when you open a PDF file in Acrobat or Reader, that the display resolution changes automatically on your system?
What version of Acrobat/Reader are you using? Do you see this same issue in other files/applications?
I look forward to hearing back from you.
Best,

[CRM] Change sales office from within an order

We've been trying to get the following to work... as you might guess, so far without success.
From within a CRM order, if we change the partner number for the department a check is being done whether that partner belongs to the same sales office. If that's not the case, the sales office has to be adjusted.
Since this might have an effect on authorization, the changing of the sales office has to be done in a separate job (action). In this job, I do the following:
- Retrieve data on the object
- crm_order_read for that object
- select the correct sales office
- prepare the crm_orgman structure with the new data
- crm_order_maintain with the crm_orgman and inputfields tables
- optionally commit work, bapi_transaction_commit etc.
For as far as we can see, the data is correct. However nothing is being changed. Ideally what I'd like to do is break into the process, change the object that's being processed in memory, and let the system do its job.
What we've also tried is (shame):
- Retrieve data on the object
- crm_order_read for that object
- select the correct sales office
- direct update the corresponding tables with the new values
This works, but as soon as we return control to the system, the changed values (verified, if we look at the tables the values are changed) are reset to what they were.
It's taking way too much hours for something that should be (in my eyes) a pretty simple action. Any suggestions? Thx in advance!

Hi Egbert,
Please take a careful look at the GUIDs you are using: if you are using the orgman structures, the REF_GUID is not the ORGMAN-GUID but instead the ORDERADM_H-GUID. Can you confirm if this has been checked and if it then still is not working? The COMMIT_WORK BAPI is also not necessary.
Kind regards,
Joost Janssens

How do I change picture resolution from screen capture?

If I want to take the image on the screen in Encore CS5 and save it as a photoshop picture the resolution is 70 DPI. Is there any way to change this resolution? I would like sharper pictures if possible, 100 DPI to 200 DPI if this can be done.
Encore CS5
Core 4 2.4 ghz processor
6 GB Ram
700 GB free on hard drive
Windows 7 64 bit

I completely agree with your goal - getting as a good a resolution print as possible. But your focus on dpi for the capture of a frame will not help you.
Kind of like scanning an image. If you are going to blow it up later you want to scan at higher resolutions than if you don't. There is of course image quality versus file size issues, etc. etc. but at least I would have the option to change resolutions on capture.
Scanning at a higher resolution adds more pixels. So, for example, scanning a finely detailed 7.2 x 4.8 inch image at 300 dpi produces 2160 x 1440 pixels. Scan a grainy photograph similarly, and it will be 2160 x 1440 and look lousy. Use a 5 megapixel camera to shoot the original scene, you've got more pixels. If you have only the SD video image, all you have is the 720 x 480 pixel image. It doesn't matter how you set the dpi on capture, just that you capture all 720 x 480 pixels.
In Premier Pro CS5 and Encore CS5 the image size is 10 inches by 6.667 inches and the resolution is 72 pixels/inch.
Pulling from womble the image size is 7.2 inches by 4.8 inches and the resolution is 100 pixels/inch.
The part you are not listing is the fact that for each of those the pixel size is 720x480. As long as you capture the 720 x 480, the resolution of the image is not improved by flagging it as 72 dpi or 100 dpi. You can change that in photoshop for either of those captures, and you get a different print size, but no more or less pixels.
In either case, re-sizing the image in photoshop doesn't change the pixels/inch resolution. I want to capture the original image in as good resolution as possible rather than having to correct it after capture.
"As good resolution as possible" is 720 x 480.

Changing Property Values from within a Function

I'm wondering how I can change a property of an instance from
within a function inside a method. I have some code here...
Basically I just need to set _lynn_idle to false when a tween is
occuring and _lynn_idle to true when the tween is finished.
Unfortunately I can't seem to simply set it to false or true inside
these listener functions like I'm able to anywhere else (seems the
variable is only local to the function when I need it to access the
variable associated with the instance). Any help is much
appreciated.

Inside callback handlers the class members go out of scope.
To remedy use a local (local to the function) reference to the
current object.

I am trying to change the datasource from the weblogic console to point to a different datasource,which is throwing the following exception....

Please help me resolve this ..

Hi,
I guess your changes did not get saved into the config.xml yet, because you have already a similar entry in config.xml file for it.
There is xml created under pending dir, everytime we try to create a DS
but it never completes and never gets saved (You will see in top left corner of weblogic console saying changes are pending something like that)
1) So, copy the DS xmls for each new DS created temporarily under jdbc dir to a temp directory
2) Now, click on the undo changes in the top left corner of your weblogic console
3) Place the DS xml file in its correct location from temporary dirctory (you did this copy in step-1 )
4) Now, Manually enter or change the DS xml filename entry in config.xml.
5) Bounce the weblogic managed servers and admin server, It will work

Hi
When I open photo's in Fireworks it automaticaly opens withe

Maybe, but it's not the way I read it. I think the issue here
is the OP
is not being very clear as to WHAT resolution he's referring
to. I tried
to clear that up in my post, but I should have replied
directly to the
OP's post rather than to yours. Sorry for the confusion. :-)

Changing Book/Page from within a pageflow

We need to define a pageflow action which has the same effect as the user clicking
on a Book (or Page) tab, i.e. switches to another portlet/pageflow - preferably
at the "begin" action.
That's probably 2 problems:
1) define an action to simulate the user clicking on Book tab
2) define book tabs so that the pageflow state is reset to the begin action
This sounds as though it may be related to howie's <"Reset" pageflow portlet state>
problem.
Just to stop you taking the easy route...
1) can be solved simply by forwarding to /portal/my.portal?_nfpb=true&_pageLabel=book_search
(where book_search is the definition label of the book I want to go to)
I don't like this because:
a) this has hardcoded the portal name, which will be different on the live server
b) it hasn't solved problem 2 because _nfpb=true has maintained the pageflow state
in book_search
2) I can lose pageflow state by removing _nfpb=true (see above), but then I don't
actually arrive at the right page!
Can anyone help?

Try
on (release) {
getURL("

Unable to Change Screen Resolution in Remote Session - Windows Server 2012 R2

Does anybody know of a way to allow Remote Desktop users to adjust their own screen resolution in a remote session under Windows Server 2012 R2? We are struggling with this and can't seem to find a solution.
When users login to their RDP session and try to adjust their screen resolution this message is displayed in Control Panel:
"The display settings can't be changed from a remote session."
We don't want to use the "make text and other items larger or smaller" scaling feature, as this produces undesirable results with some of our applications. We also don't want to have to support multiple types of RDP clients or RDP shortcut
files.
We have looked at other posts but can't find an answer that applies to Windows Server 2012 R2. The closest thing we could find is KB2726399, but it only applies to Server 2008.
Does anybody have a solution for Server 2012?
Thanks

Hi,
Currently you cannot change the resolution from within the session. This is normal and expected behavior.
Unfortunately this means you need to set the desired resolution before connecting by using custom .rdp files, manually within the Remote Desktop Client, custom web launch page, custom windows launch program, etc.

How to edit GRUB boot options from within Arch.

Hello!
I'm having a problem with scanlines (both in X and tty), and I think that the solution is the vga= boot option. I, however cannot edit the GRUB boot options from within GRUB, because the commands go off my screen (overscan.)
I was wondering if there is a way to edit the default GRUB options from withing Arch. I have GRUB on /dev/sdb0 and chainload with the windows bootloader, it it matters.
Thanks,
wesleyac.

Thanks.
I cannot seem to figure out how the steps here translate to grub.cfg settings. If you could explain this to me or point me to somewhere that does, I'd appreciate it.
qinohe:
Thanks! I actually ran into a page that mentioned grub.cfg, but at the top of my grub.cfg, there's a big warning saing not to edit it. Should I ignore that?

Changing screen resolution

Hi Everyone,
I'm quite sure that it is not possible to change the screen resolution from within a running java program. The problem is that my boss won't believe it until he reads it in the spec. Does anyone out there know where to find a anything about it the specs?
Thanks in advance
jan

Hi! The screen resolution is a function of the underlying OS and cannot be changed from a Java program, unless one resorts to JNI. However, the screen resolution can be retrieved from a Java program. Look at the docs for the getScreenSize() and getScreenResolution() methods in the java.awt.Toolkit packges. Note that these methods are abstract. The actual implementation depends upon the vendor.
Perhaps you can ask your boss to search the Java docs for methods that allow Java code to change the resolution w/o resorting to JNI. We'll all be glad to know! :-)
Hope this helps!
Cheers!

HP Officejet 8600 Pro - how to change scan resolution presets at the printer

I have an HP Officejet 8600 Pro and wish to scan to email from the printer and wish to change the default resolution setting. I would like to change the default scan resolution so I dont have to remember to change it every time I scan.
If I change it with the HP Windows Printer Assistant software it only seems to change the resolution for this time and only from the computer not at the printer.
Is it possible to change the scan resolution settings at the printer? I cant find detail in the manual or on the printer console.

bvlusa,
Open the Icon labeled Officjet Pro 8600 on your desktop, and then click on Scan a Document or Photo. When the Scan application window opens you can change the Resolution from the drop down menu.
I hope this helps.

Is it possible to change application state from a component?

I was wondering if it is possible to change application state from within a custom component and if so, what would the syntax be if I had an application named "zzz" and I wanted to change the app state from "state1" to "state2" from my component?
Thanks!

Hi,
you always have a static class Application.
Application.application will be the root component. After that you can change it state.
Application.application.currentState = "state2";
But it's not the best way to change states. It's better to dispatch events from components and change states in listeners.

In Lightroom 4, is it possible to change the resolution when exporting to Facebook?

Is it possible to change the resolution when exporting a photo to Facebook using either the regular plugin or Jeffrey Friedl's plugin? I can't seem to do it; I only have control over the image dimensions, not the resolution and the dimensions, as you can see in the screen shots below:
I have control over both when I export to my hard drive (or a flash drive, etc.), as you can see below:
I can't find the option to control the resolution when I try to export to Facebook. Before I got Lightroom 4, I would create whole new low-resolution files of images I wanted to post online using Photoshop. The image size settings I would use are a longest edge of 10 inches at 72ppi, and I would like to continue doing this. If I can only set the longest side to 720 pixels (I can't even seem to set the longest edge to an inches value - I can only choose a pixels value) and not change the resolution from 300ppi to 72ppi, then my photos' longest edge will only be less than 3 inches long (right?). Thus, I really want to be able to upload low-resolution photos to Facebook via Lightroom with the ability to change both the resolution and the image dimensions. Any idea how to do it without having to export to my hard drive first? Thanks!

You can set it to whatever you like, and it makes no difference. Most of the time (depending on how you saved it), it will still open as "72".
When you save an image for web, the resolution is usually stripped from the file. It's simply not there anymore. That's probably what happens in the Lr facebook module, and that's why there's no entry for it.
But when you open that image somewhere else, that default of 72 ppi is assigned. Most apps need to know what to do with a file if asked to print it out. So there is a default, and that's usually 72, mostly by convention. With that default ppi, it prints out at a comparable size to what you see on screen at 1:1 display.
And when people see that, they think "hey, web images are 72 ppi". But they're not - that figure is just inserted there by the opening application.
