I have 2 monitors on Nvidia Card: - First: 1440x900 - Second: 1280x1024 The first one works great.  The second one has a resolution of 640x480.  In Nvidia settings, I can choose only 640x480.  If I change ViewportOut, it drops to 640x480. It would be very cool if I could change resolution in xorg.conf.

Slax uses X.org for managing its GUI. However, when I boot Slax (specifically in a VM), the resolution gets capped at 1024x768. How can I increase the resolution to more fully utilize the screen estate available on my display? I have already attempted to follow the old advice from the following sources: - http://old.slax.org/forum.php?action=view&parentID=25516 - http://www.linuxquestions.org/questions/mandriva-30/changing-screen-resolution-552768 - http://slaxlive.blogspot.com/2005/07/slax-linux-step-by-step-first-step.html

I'm running Tails. - Can't use the settings menu to do it, there's only one option there and it's like 600x800 which is the problem, I think - Can't figure out what the display name is for my monitor, have tried using w but it tells me my console's not wide enough to do it. I cannot make the window bigger because of my screen resolution. It already looks huge. - All the solutions I've found involve using xrandr, but I need to know the display name of my monitor to do them. I have run out of ideas.

While using Xorg X11, on KDE/Gnome/XFCE **how can we scale the display/resolution** for the whole desktop and/or per application? **(when this is not available on the settings GUI)** The purpose is to keep the screen resolution unchanged (at max) while scaling the size (bigger/smaller) of the desktop/applications.

I'm running MX Linux and Windows on the same machine. I'm using an LCD television screen connected via HDMI to the graphics card (NVIDIA GeForce RTX 2070 SUPER). **My problem:** - On Windows, I can select resolutions way higher than 1024x768 (i.e. 1920x1080 and above). - However, on MX Linux, 1024x768 is the highest resolution (800x600 and 640x480 are also selectable). - Display settings in MX Linux only show one screen labelled "default". **I tried:** - using xrandr as described here . - "xrandr --newmode (...)" gives the error(/warning?): "Failed to get size of gamma for output default". - "xrandr --addmode default "1920x1080_60.00"" also gives "Failed to get size of gamma for output default". - "xrandr --output default --mode "1920x1080_60.00"" gives the **additional** message: "Configure crtc 0 failed". - no change in display happened after that. - using arandr (GUI) *after* typing the above commands: - "default" is shown as screen - right-click --> resolution: shows the 3 resolutions mentioned above, *and also* "1920x108060.00" - selecting "1920x108060.00" and hitting the check sign --> pop-up error message: "(...) error code 1: xrandr: Failed to get size of gamma for output default" and "xrandr: Configure crtc 0 failed". - no change in display happened after that. I would appreciate any help. It is kind of inconvient having to work with this low (and stretched!) resolution on a 42'' LCD TV screen ;)

After I set GRUB_GFXMODE it affected GRUB menu and some of subsequent printouts, but in the middle of boot, text becomes very small again, and I still want to make resolution smaller. Where else the resolution is changing during boot? Any usage of fbmode reports unknown mode or invalid argument:

$ sudo fbset 1920x1200-32
Unknown video mode `1920x1200-32'

$ sudo fbset 1920x1200

$ sudo fbset 640x480-60

$ sudo fbset 640x480

$ sudo fbset 640x480-8

and so on.

I'm trying out [WPS Office](http://wps-community.org/) (version Alpha21 10.1.0.5672~a21). The first issue I'm running into is a display bug: the display is compressed horizontally (or elongated vertically, whichever). Only the document display is affected, the user interface part is fine. This isn't a font issue: I see this with every font, and with figures. In the screenshot below, the blue rectangle is in fact a 1cm×1cm square, and the PDF output is correct. On startup, WPS Office shows a “System Check” window which mentions > System DPI is asymmetric. WPS Office may have display issues. The “solution” link leads to http://community.wps.cn/wiki/dpix_not_equal_dpiy which is a broken link. If the solution exists anywhere on the web now, I can't find it (possibly because it's in Chinese only). xrandr output (that's actually 158dpi both horizontally and vertically, so whatever WPS Office is doing to determine the resolution, it's mistaken): Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 32767 x 32767 eDP1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 309mm x 173mm I use Sawfish without a destkop environment. [Fouad](https://unix.stackexchange.com/users/247050/fouad) reports that he has the same issue under XFCE, but not under Cinnamon. How can I make WPS Office display document content at a correct aspect ratio?

My problem is that I cannot set the resolution on my external monitor (LG 34UM95-P) to 3440 x 1440 when I connect the laptop with the monitor via HDMI. The maximum that I get is 1980 x 1080. Interestingly, when I connect the monitor via a USB-C dongle, it sporadically works with the 3440 x 1440 resolution (I need to plug/unplug multiple times for this to work). Most of the time, I only get a black screen though. Here is what I have tried so far: - Changed the HDMI cable (e.g., used HDMI 2.1 cable). Did not solve the issue. - Checked with different laptops. On the Macbook Air M4 it works, on a Dell (Intel Arc; same GPU) with Ubuntu it does not work. - Checked with a different OS on the same laptop. It works on my Lenovo when I install/use Windows 11. - Installed the latest firmware and OS updates. No changes. I am running out of options. I believe that this is a driver problem with the Intel Arc GPU, but I am not sure how I can solve this issue since my drivers are all up to date.

I have installed Debian 7.2 from liveUSB and connected the monitor Samsung SyncMaster SA850 with DVI cable into integrated Intel HD graphics. However I have very low resolution and can't change it. In addition, the system doesn't want to shut down (drivers update didn't help). With VGA cable everything works fine. Configuration: I have ASUS H87-Pro motherboard and Intel Core i7-4770K. Linux kernel 3.2.0-4-amd64

Connecting an ASRock Beebox N3000 with Lubuntu 16.04 to a Sony Bravia with a HDMI cable this is the output of xrandr: Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767 DP1 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) DP3 disconnected (normal left inverted right x axis y axis) HDMI1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 735mm x 420mm 1920x1080i 50.00*+ 60.00 59.94 1280x720 60.00 50.00 59.94 720x576 50.00 720x576i 50.00 720x480 60.00 59.94 720x480i 60.00 59.94 640x480 60.00 59.94 HDMI2 disconnected (normal left inverted right x axis y axis) HDMI3 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis) 1920x1080i is supposed to work well, but it results in a too wide desktop, such that it does not stay within the screen limits. Another laptop connected by VGA performs reasonably well with 1360x768, but this resolution is not supported here. xrandr --addmode HDMI1 1360x768 results in xrandr: cannot find mode "1360x768" don't know if this modeline can be added. I have also tried to change the TV configuration, but there's little to do under a HDMI connection.

I've started using the Win-Kex package in order to create a GUI for WSL2 Kali Linux. It runs okay, however the tigerVNC viewer appears blurry & hard to read. After investigating, I discovered that it is caused by Windows scaling and layout setting (which is set to the default of 150%). If I change this to 100% Kali Linux appears fine, however then Windows icons and text is too small. I knew there used to be a trick to change the high DPI settings for individual apps (however, as the exe is hosted in WSL I am unable to use this setting) Any idea's on how to fix this? Thanks, Jack

I need to increase screen resolution to 1024x800 for my XEN console. I tried to place vga=791 at the end of kernel line the file /boot/grub/grub.conf but it seems that most of the boot arguments are ignored during startup. Probably inside XenSever /boot is not really used in order to launch CentOS. I even tried to add boot option in the boot option tab (VM -> Property -> Boot Option) but doesn't work.

i'm trying to set a specific resolution for kms, at boot time. by default kms choose the highest resolution available (2500x1600) which is a bit hard to read. i'd like to set 1440x900 instead. i tried two things via grub, the first one:

GRUB_GFXMODE=1440x900
GRUB_GFXPAYLOAD_LINUX=keep
GRUB_GFXPAYLOAD_LINUX=1440x900

but that didn't help, the system act just the same, no matter if it is there or not, it just continue to use 2500x1600. the other thing i tried instead is setting a kernel parameter like so:

GRUB_CMDLINE_LINUX_DEFAULT="video=1440x900"

that kind of helped a bit, the resolution changed, it's much better and readable but then, the virtual_size didn't change accordingly, it's still 2500x1600, meaning my tty is much bigger than the screen itself and so i only see the upper_left part of a larger term. how can i force kms to a specific resolution ? thanks

I have a display that supports 280 Hz and although I'm limited to an old Intel HD610 via HDMI, **on Windows I'm able to set the refresh rate up to 120 Hz** (checked on display menu), but on Linux I can only go to 99 Hz maximum. What I'm doing: cvt 1920 1080 120 Which prints: # 1920x1080 119.93 Hz (CVT) hsync: 139.12 kHz; pclk: 369.50 MHz Modeline "1920x1080_120.00" 369.50 1920 2080 2288 2656 1080 1083 1088 1160 -hsync +vsync Then: xrandr --newmode "1920x1080_120.00" 369.50 1920 2080 2288 2656 1080 1083 1088 1160 -hsync +vsync And: xrandr --addmode HDMI1 1920x1080_120.00 Finally, when I try to set this custom refresh rate (via Xfce Display app), nothing happens; it goes back to the previous refresh rate.

As we see, the resolution/density tags are missing. So let's add them, using https://unix.stackexchange.com/a/791125 :

As we see, the page size is wrong. In Postscript points, the right size would have been 595 × 842 pts. What's going on here? Are we overusing exiftool+convert, or is convert simply wrong? We might suspect that we shouldn't need to tell the toolchain the density/resolution more than once. However, (in the ideal world) you should be able to say as often as you wish how big your pixel or your dot is (in our case, 1/600 of an inch wide and 1/600 of an inch high) to any tool in the toolchain.

I just installed Debian 11.6 and see that everything looks scaled up a lot. I checked the size of the display and it is 800 x 600 which is quite big having it on my 4k monitor. But me having an NVIDIA RTX 3060 Ti should not trigger this because that is some good hardware. I opened Settings and went to the Display section to change the resolution and I can only see the resolution but not change it. How can I change the resolution of the display?

For example, I've application (game) that has only 640x480 resolution. Now I've 2 options: launch it in window-mode, and will has 640x480 size or enable fullscreen and will fill all screen. What I want is to resize application without going fullscreen (e.g. to 1024x768). As for now I've tried 2 solutions: 1. Enable 'Emulate a virtual desktop' in winecfg. At first it will launch desktop with that resolution, but when I enable fullscreen in application it will shrink that desktop to 640x480. 2. Start Wine in inner X-server: Xephyr -ac -br -noreset -screen 1024x768 :1.0 & ZEPHYR_PID=$! sleep 1 DISPLAY=:1.0 wine game.exe kill $ZEPHYR_PID Same problem here, it will resize window when I enable fullscreen.

I use a Dell XPS 13 laptop with a 4k screen. I only ever use in FHD resolution. Whenever I connect an external screen that I've not used before (this happens surprisingly often), Mint autodetects the new screen, sets it to FHD (good), but sets the built-in screen to 4k (bad) with a user interface scale of 200% (also bad), so I have to access display settings, switch to FHD and do resize many open windows. Not the end of the world, but tedious. Is there a way to tell Mint which resolution and scale to use by default on my built-in screen, i.e. to retain FHD and 100% scale on the built-in display, regardless of the kind of external display I connect?

I installed Debian 8.3 LXDE today and I cannot adjust the resolution of my monitor. I have a 1920x1080 resolution, but allows you to install Debian to me only 1280x1024. I tried to make as here: https://wiki.archlinux.org/index.php/xrandr , using xrandr to do manually, but there is no connected interfaces: drahenfels@debian:~$ xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 640 x 400, current 1280 x 1024, maximum 1280 x 1024 default connected 1280x1024+0+0 0mm x 0mm 1280x1024 0.00* 1152x864 0.00 1024x768 0.00 800x600 0.00 640x480 0.00 720x400 0.00 My GPU: AMD/ATI RS780L [Radeon 3000]
