[Ubuntu-x-swat] [Bug 1973093] [NEW] xmessage loses text area as buttons are added and -g
Public bug reported: xmessage text gets obscured with option combinations using buttons and geometry specifications. Quick background: xmessage creates a new grey window with a white text box inside it. Without -buttons, the white text box usually spans the full width of the grey window that contains it, leaving no margins. Things start going wrong when you start specifying -buttons or -g (geometry), and text can end up being obscured. Problem #1: If the width of all the buttons you specify makes the grey window wider than the text, the white text box does not increase in width to match. You end up with an undesirable wide grey margin on the right side of the white text box. If you resize the window, making it less wide, the grey margin does not narrow; it moves in and covers and obscures the text, even though there is plenty of room for the text. Suggested Fix #1: The white text box must always be created the same width as the window that contains it, with no useless grey margin to the right. Narrowing the width of the window should not cause text to be obscured by a wide and useless fixed grey margin. Reproduce: xmessage -buttons 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20 "123456789" Problem #2: If you add a -g (geometry) option and specify just the width (not the height) for a window with buttons wider than the text box, the obscuring grey margin persists. If you add a "-g NNN" option, where NNN is the width that xmessage would have chosen itself, then you get exactly the same unpleasant behaviour as Problem #1 above. If you increase the NNN to be wider that what xmessage would have used, then both the window and the text box width are created increased by that amount, as if you had resized the window with a mouse. The useless grey margin to the right of the text box stays the same width, just as in Problem #1. If you decrease the NNN to be narrower that what xmessage would have used, then both the window and the text box width are created decreased by that amount, as if you had resized the window with a mouse. Not all buttons will show; this is expected. What is not expected is that the useless grey margin to the right of the text box stays the same width, and so it now overwrites and obscures the text, even though there is plenty of room for the text. If you resize the window back so that all the buttons show, all the text also shows and we're back to Problem #1 above. Suggested Fix #2: Same as above. Reproduce (width 541 is my xmessage chosen width for font "fixed"): xmessage -g 400 -buttons 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20 "123456789" xmessage -g 541 -buttons 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20 "123456789" xmessage -g 700 -buttons 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20 "123456789" Problem #3: If you add a -g option and specify both the width *and* the height for a window with buttons wider than the text, things get much worse. If you add a "-g NNNx55" option, where NNN is the width that xmessage would have chosen itself and "55" is about the same height, you would expect to get exactly the same results as if you didn't specify any geometry at all. That's not what happens. You get a fixed-width text window about 12 characters wide, with a huge grey margin on the right. It doesn't matter what size text you specify; the white text box will be created about 12 characters wide and any text to the right of that will be masked and obscured by the wide grey margin. Changing the width of the window has all the problems of Problems #1 and #2 above. Suggested Fix #3: Same as above. Specifying a geometry that is identical to what xmessage would have chosen itself should create an identical window. Text should not be obscured. Reproduce (width 541 is my xmessage chosen width for font "fixed"): xmessage -g 541x55 -buttons 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20 "123456789-123 YOU DON'T SEE THIS" ProblemType: Bug DistroRelease: Ubuntu 22.04 Package: x11-utils 7.7+5build2 ProcVersionSignature: Ubuntu 5.15.0-30.31-generic 5.15.30 Uname: Linux 5.15.0-30-generic x86_64 ApportVersion: 2.20.11-0ubuntu82 Architecture: amd64 BootLog: CasperMD5CheckResult: unknown CompositorRunning: None CurrentDesktop: ubuntu:GNOME Date: Wed May 11 17:12:52 2022 DistUpgraded: 2022-04-04 16:21:26,723 DEBUG Running PostInstallScript: '/usr/lib/ubuntu-advantage/upgrade_lts_contract.py' DistroCodename: jammy DistroVariant: ubuntu DkmsStatus: v4l2loopback/0.12.5, 5.15.0-29-generic, x86_64: installed v4l2loopback/0.12.5, 5.15.0-30-generic, x86_64: installed GraphicsCard: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Fujitsu Limited. 2nd Generation Core Processor Family Integrated Graphics Controller [10cf:15f5] InstallationDate: Installed on 2020-09-08 (610 days ago) InstallationMedia: Ubuntu 20.04.1 LTS "Focal Fossa" - Release amd64 (2

I see corruption that changes depending on to which of the three LCD screens I drag my Firefox window. The worst corruption is far right. I see less corruption when I drag the window to the middle LCD, and dragging the window to the leftmost LCD looks fine. The middle and right LCDs are on the same ATI FireMV 2250 card. The leftmost LCD is on a second FireMV 2250 card. The corruption isn't constant. Things look fine when I first reboot and get worse as time goes on.

I said: > The corruption does disappear when I slide the window containing the > corruption onto either of the other monitors, Today, I have some corruption (on the zero glyph in a particular font at a particular size) that stays corrupt when I slide the Firefox window from the Right monitor to the Middle monitor (which crosses from the first FireMV to the second). But this corruption vanishes when I keep sliding from the Middle to the Left monitor, both of which are on the same FireMV card. (And the corruption returns when I slide the window back to Middle or to Right.)

madbiologist - alas, I don't have a "non-production" machine on which to try the beta. The corruption does disappear when I slide the window containing the corruption onto either of the other monitors, which are on the second FireMV 2250 card. I suppose I should swap cards and see if the corruption swaps, in the off chance that it might be hardware. If the bug report doesn't belong grouped here, I wonder where it should go.

[Ubuntu-x-swat] [Bug 556782] Re: [rs690m] Graphics corruption with ati x1200
Ubuntu 10.4 user with a pair of ATI FireMV 2250 cards (RV516 chip) running Xinerama across three monitors (one monitor output is unused) using radeon driver on an AMD-64 2.6.32-24-generic. Over time, single characters in Firefox get mangled - in tab titles and on the displayed web pages. Typing those characters into text boxes also shows the mangling. Changing the Firefox font size up or down (CTRL-plus, CTRL-minus) restores the characters to good at the new size; setting the font back to the original size (CTRL-zero) returns the mangling again. Sometimes the characters disappear entirely. Restarting Firefox didn't help until I added "Option "AccelMethod" "XAA" to my xorg.conf file; now, restarting Firefox clears the font problem. (It didn't before - I had to restart the X server.) Also, while paging through photos in Facebook, twice now (separate instances of Firefox some time apart) a photo has drawn itself about 200 pixels up and to the left of where it should be in on Facebook web page, even outside of the browser window. Dragging other windows across the corrupt area cleared out the ghost photo. Also, a few times going to a video in YouTube (in Firefox) would display a non-functional static image of slewed black-on-white, similar to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/556782/+attachment/1283506/+files/Screenshot-3.png. (Other people have called this "video static", but it is seems to be a wrongly displayed image, not white noise.) Restarting Firefox cleared that up. I didn't have any of these problems when I ran a single FireMV 2250 with an Nvidia card for the third monitor, but that was on a previous kernel (2.6.32-23-generic) as well. It's the dual 2250 (on the new kernel) that is now misbehaving.

[Ubuntu-x-swat] [Bug 591104] [NEW] wrong xinerama scroll/pan using two cards three monitors
Public bug reported: Binary package hint: xorg Xinerama has a bug/behaviour in 10.4 Lucid that wasn't there in 9.10. http://ubuntuforums.org/showthread.php?p=9417686 Under 10.4 Lucid using Xinerama with two monitors (Left,Middle) on an ATI card (FireMV 2250 with "radeon" driver) and the third monitor (Right) on an nVidia card (G86 GeForce 8300 GS with "nv" driver or "nvidia" driver). I did not have this problem under 9.10 Karmic. With Xinerama turned off, the mouse moves perfectly between all three monitors - the two monitors on the ATI card (Left,Middle) and the single monitor on the nVidia card (Right). Unfortunately, it splits my desktop into two DISPLAYs (ATI and nVidia) and so I can't move windows between the two. Under 10.4, with Xinerama on, Left and Middle start out showing the same content. (This looks like mirror mode, but isn't.) Starting on Left, I can move the mouse to the right, and it crosses both Left and Middle simultaneously until it reaches the right side of both. Then, the mouse leaves Left and we discover that Middle is actually a scrolling double-width screen with only a single width showing - as I move against the right edge of Middle, the mouse causes Middle to scroll/pan, until both virtual Middle screens have been crossed, then Middle stops scrolling and the mouse moves onto the Right monitor. At this point, with the mouse all the way to the right, I have three monitors showing three different 1600x1200 parts of the full 4800x1200 Xinerama desktop. Moving the mouse back toward the left from the Right monitor, the mouse crosses Right, leaves Right and moves onto the right edge of Middle, and crosses left across Middle, then when the mouse hits the left side of Middle, the mouse also appears on the right side of Left, and as I continue to move the mouse left, the mouse crosses Left and Middle scrolls/pans until it is showing exactly the same content as Left. At this point, with the mouse all the way to the left, I have Left and Middle mirroring each other (wrong) both showing the leftmost 1600x1200 of the full 4800x1200 Xinerama desktop and Right continues to show the rightmost 1600x1200. The middle 1600x1200 is no longer visible on Middle. I need to find out how to tell Middle not to scroll and to show only the right side of its double-size viewport. This didn't happen under 9.10.
