Initialization of applications GTK vs. Qt
I am running the Mate desktop on CentOS 7 and trying to get fcitx working so I can switch between two western keyboards and typing pinyin. Unfortunately the instructions on the net are lacking and the graphical configuration tool for fcitx is missing from EPEL. At this stage, I have, with the support of one person on the CentOS mailing list who types Japanese, got it working in: - terminal windows and - an application using Qt, KeePassX. I have not been able to get three applications using GTK working: Firefox, Thunderbird and LibreOffice. I can get them working when I have the three environment variables preceding the name of the application but not when launched from the desktop. I suspect GTK and Qt applications are initialized differently - perhaps by X - but I do not know how to resolve this. Any pointers or ideas for further research are appreciated! Thank you.___ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: https://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s

The external monitor is an Acer S230HL monitor running at 1920 x 1200 and connected via HDMI at bot ends, ie. including the laptop HDMI port which xrandr misidentifies as DP-1.

Fwd: Re: Xrandr and external monitor
With the possibility of an update of xorg, I'd like to bring up my problem again. I am looking for suggestions on how I should debug this to find if this is a xorg problem or the issue lies somewhere else. Thanks.

So the problem could lie with x or with the video driver, the latter reporting to X? According to X.org.log I am running X Server 1.20.11. One of my concerns is why X reports that DP-1 connection is used with the external monitor whereas it in reality uses HDMI without any adapters. That suggests something is reported incorrectly which could conceivably lead to some other problem. I am attaching X.org.log which to me seems to suggest that it is using the noveau driver. Note that I just tried to disconnect/reconnect the external monitor but could not find any log of that connection towards the end of the log.

I have tried bot booting with the external monitor already attached and attaching/reattaching it later. No SVGA plugs. The monitor is an Acer S230HL monitor. I am using the nouveau driver and inxi reports the presence of both Intel UHD Graphics 620 and Nvidia GM108M (GeForce 940MX).

Yes, I have done so using xrandr. However, it does not work by just listing the resolution 1920 x 1080 for the external monitor, I have to add scale 2x2 to the xrandr command. Even so, the wallpaper background scales oddly, does not repeat in a consistent fashion on the display, and, while I can drag a window opened on the laptop display over to the external monitor and it looks ok, if I maximize it, it does not fill the entire monitor but only 1/4. If I open eg. a terminal window, it also scales to 1/4 of the surface. Clearly there is/are bug(s) but where? I surmise it's because the laptop display is UHD at 3840 x 2160 and the external monitor runs at /lower/ resolution. Most often the opposite is true. I would love to help find the bug/bugs and get this working!

Xrandr and external monitor
Running the latest version of Rocky Linux fully updated and Mate on a Dell Inspiron 7570 laptop with a UHD display, i.e. 3840 x 2160 pixels. I would like to attach two external monitors and initially experimented with a Dell dock model 3100 and the latest version of the DisplayLink and evdi drivers. However, although the Mate display applet shows the correct resolution for the laptop display itself and for the external monitor which is running at 1920 x 1080 pixels, the resolution on the second, external display is more like 640 x 480 pixels. While I initially thought this was due to a bug in the DisplayLink/evdi drivers, I see the same issue when I connect the monitor directly to the HDMI output on the laptop itself, ie. DisplayLink/evdi are presumably not involved although they are installed, nor is the dock of course. I just discovered running xrandr --listmonitors that, while the internal laptop monitor is labeled eDP-1, xrandr identifies the external monitor as using DP-1 although it uses the laptop HDMI-connector. Further, while mate hardware display monitor also identifies it as using DP-1 - possibly based on xrandr output - the monitor itself tells me it is connected using its HDMI1 connector. xrandr does report the correct display resolution, though. Thus, it looks like xrandr misreads the configuration feeding it to mate. But, I guess it could also be the BIOS perhaps? I just updated the BIOS to the very latest version and saw no difference. Could this be an X11 bug (I am indeed running X11 and not Wayland)? How should I troubleshoot it? Appreciate ideas!

My laptop running Rocky Linux 9 and Mate desktop has a UHD display running at 3840 x 2160 resolution whereas my external monitor runs at 1920 x 1080. I cannot get the external monitor to use this latter resolution, at startup it seems to default to 640 x 480 or similar Does anyone have experience with an external display running at a lower resolution than the laptop display itself?

I understand your issue but did not know if a laptop was involved. I am hoping to find someone with a laptop with a UHD display and an external monitor running at a /lower/ resolution. I need to be able to establish where the problem lies, with: (1) Mate; (2) X; or (3) the video driver...
Sending the clipboard content to another application
Hello list, warning: I'm a beginner in X GUI matters. The only thing I managed is to send give the input focus and sending the Ctrl+v key (from Emacs under XFCE) to other windows. This is working in principle but my target application (Ansys, a tcl/tk frame) requires additionally a Return key to digest the input. The problem is now that the Return key arrives earlier then the clipboard content and I don't have any idea how to wait for the right moment to send it. Thanks Dieter -- Best wishes H.

xserver-xorg-ati does not reactivate monitor after hibernate
I'm running Linux Mint 17.2 with a Radeon HD 5770 card. When I restart the computer after hibernating, the monitor remains in low-energy mode. That means it is not receiving a signal from the card. I have tried pressing Ctrl+Alt+Del, which should bring up the Quit dialog with the Shutdown button as focus. And sure enough, after I press RETURN, the computer shuts down. I have also tried Ctrl+Alt+F1 but the monitor remains off. If I type blindly, I can log in and enter `sudo shutdown -r now` and sure enough, the computer reboots. Everything seems to be working but the monitor signal. What can I do to fix this? -- Don't stop where the ink does.
