This is probably an upstream bug. To make sure it is not due to any configuration "remnants" in my xrdb database, I have emptied it and checked (with 'xrdb -query') that it really does not contain anything related to xterm. Then I ran a simple xterm -j which produced: Warning: Cannot convert string "on" to type Int The same Warning occurs with my XTerm and XTerm-color resource files in place. Reason ====== Obviously, the '-j' option on the command line sets a corresponding X resource to 'on'. The man page says '-j' "corresponds to the jumpScroll resource" - but I could not find any jumpScroll: on in my /usr/share/X11/app-defaults/XTerm /usr/share/X11/app-defaults/XTerm-color resource files - so this must be set to 'on' somewhere internally in xterm, as soon as one passes '-j' on the command line. However, due to some change somewhere else in the code, xterm expects an integer and not an 'on' or 'off' - that's what the warning says. Prepending 'strace' to the invocation, I can narrow it to the following: ... openat(AT_FDCWD, "/usr/local/share/cursors/xorg-x11/jaguarx/cursors/left_ptr", O_RDONLY) = 4 fstat(4, {st_mode=S_IFREG|0644, st_size=4160, ...}) = 0 read(4, "Xcur\20\0\0\0\0\0\1\0\1\0\0\0\2\0\375\377 \0\0\0\34\0\0\0$\0\0\0"..., 4096) = 4096 lseek(4, 0, SEEK_SET) = 0 read(4, "Xcur\20\0\0\0\0\0\1\0\1\0\0\0\2\0\375\377 \0\0\0\34\0\0\0$\0\0\0"..., 4096) = 4096 read(4, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 4096) = 64 close(4) = 0 poll([{fd=3, events=POLLIN|POLLOUT}], 1, -1) = 1 ([{fd=3, revents=POLLOUT}]) writev(3, [{iov_base="5 \4\0\2\0\200\6\311\1\0\0 \0 \0007r\4\0\3\0\200\6\2\0\200\6\0\0\0\0"..., iov_len=4220}, {iov_base="XFIXES", iov_len=6}, {iov_base="\0\0", iov_len=2}], 3) = 4228 poll([{fd=3, events=POLLIN}], 1, -1) = 1 ([{fd=3, revents=POLLIN}]) recvmsg(3, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\1\0\26\0\0\0\0\0\1\211V\212\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0", iov_len=4096}], msg_iovlen=1, msg_controllen=0, msg_flags=0}, 0) = 32 poll([{fd=3, events=POLLIN|POLLOUT}], 1, -1) = 1 ([{fd=3, revents=POLLOUT}]) writev(3, [{iov_base="\211\0\3\0\5\0\0\0\0\0\0\0", iov_len=12}, {iov_base=NULL, iov_len=0}, {iov_base="", iov_len=0}], 3) = 12 poll([{fd=3, events=POLLIN}], 1, -1) = 1 ([{fd=3, revents=POLLIN}]) recvmsg(3, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\1\0\27\0\0\0\0\0\5\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0", iov_len=4096}], msg_iovlen=1, msg_controllen=0, msg_flags=0}, 0) = 32 openat(AT_FDCWD, "/usr/share/X11/XtErrorDB", O_RDONLY) = -1 ENOENT (No such file or directory) getuid() = 0 geteuid() = 0 getuid() = 0 write(2, "Warning: ", 9Warning: ) = 9 write(2, "Cannot convert string \"on\" to ty"..., 38Cannot convert string "on" to type Int) = 38 write(2, "\n", 1 ) = 1 poll([{fd=3, events=POLLIN|POLLOUT}], 1, -1) = 1 ([{fd=3, revents=POLLOUT}]) writev(3, [{iov_base="\211\27\5\0\5\0\200\6\10\0\0\0left_ptrb\0\6\0\17\0\200\6", iov_len=28}, {iov_base="XFree86-Bigfont", iov_len=15}, {iov_base="\0", iov_len=1}], 3) = 44 From the above, xterm succeeds in setting the X cursor to 'jaguarx', then, after some reads and polls, it tries to open /usr/share/X11/XtErrorDB, without success - and then issues the Warning "Cannot convert string "on" to type Int". Whether the absence of XtErrorDB is the cause of the Warning, or just a 'collateral' is not clear to me.
